Update to libuv commit 3ca382.

This patch changes libuv's gyp build system to
make it's own makefiles. To generate them for rust,
run these commands. They requires python 2.x to
work:

$ mkdir -p src/rt/libuv/build
$ svn co http://gyp.googlecode.com/svn src/rt/libuv/build/gyp
$ ./etc/src/gyp_uv

+# libuv
+
+libuv is a new platform layer for Node. Its purpose is to abstract IOCP on
+windows and libev on Unix systems. We intend to eventually contain all
+platform differences in this library.
+
+http://nodejs.org/
+
+## Features
+
+Implemented:
+
+ * Non-blocking TCP sockets
+
+ * Non-blocking named pipes
+
+ * UDP
+
+ * Timers
+
+ * Child process spawning
+
+ * Asynchronous DNS via c-ares or `uv_getaddrinfo`.
+
+ * Asynchronous file system APIs `uv_fs_*`
+
+ * High resolution time `uv_hrtime`
+
+ * Current executable path look up `uv_exepath`
+
+ * Thread pool scheduling `uv_queue_work`
+
+In-progress:
+
+ * File system events (Currently supports inotify, `ReadDirectoryChangesW`
+   and will support kqueue and event ports in the near future.)
+   `uv_fs_event_t`
+
+ * VT100 TTY `uv_tty_t`
+
+ * Socket sharing between processes `uv_ipc_t`
+
+
+## Documentation
+
+See `include/uv.h`.
+
+
+## Build Instructions
+
+For GCC (including MinGW) there are two methods building: via normal
+makefiles or via GYP. GYP is a meta-build system which can generate MSVS,
+Makefile, and XCode backends. It is best used for integration into other
+projects.  The old (more stable) system is using Makefiles.
+
+To build via Makefile simply execute:
+
+    make
+
+To build with Visual Studio run the vcbuilds.bat file which will
+checkout the GYP code into build/gyp and generate the uv.sln and
+related files.
+
+Windows users can also build from cmd-line using msbuild.  This is
+done by running vcbuild.bat from Visual Studio command prompt.
+
+To have GYP generate build script for another system you will need to
+checkout GYP into the project tree manually:
+
+    svn co http://gyp.googlecode.com/svn/trunk build/gyp
+
+Unix users run
+
+    ./gyp_uv -f make
+    make
+
+Macintosh users run
+
+    ./gyp_uv -f xcode
+    xcodebuild -project uv.xcodeproj -configuration Release -target All
+
+
+## Supported Platforms
+
+Microsoft Windows operating systems since Windows XP SP2. It can be built
+with either Visual Studio or MinGW.
+
+Linux 2.6 using the GCC toolchain.
+
+MacOS using the GCC or XCode toolchain.
+
+Solaris 121 and later using GCC toolchain.

-
-# `uv_handle_t`
-
-This is the abstract base class of all types of handles. All handles have in
-common:
-
-* When handles are initialized, the reference count to the event loop is
-  increased by one.
-
-* The user owns the `uv_handle_t` memory and is in charge of freeing it.
-
-* In order to free resources associated with a handle, one must `uv_close()`
-  and wait for the `uv_close_cb` callback. After the close callback has been
-  made, the user is allowed to the `uv_handle_t` object.
-
-* The `uv_close_cb` is always made directly off the event loop. That is, it
-  is not called from `uv_close()`.
-
-
-
-# `uv_tcp_server_t`
-
-A TCP server class that is a subclass of `uv_handle_t`. This can be bound to
-an address and begin accepting new TCP sockets.
-
-    int uv_bind4(uv_tcp_server_t* tcp_server, struct sockaddr_in* address);
-    int uv_bind6(uv_tcp_server_t* tcp_server, struct sockaddr_in6* address);
-
-Binds the TCP server to an address. The `address` can be created with
-`uv_ip4_addr()`. Call this before `uv_listen()`
-
-Returns zero on success, -1 on failure. Errors in order of least-seriousness:
-
-* `UV_EADDRINUSE` There is already another socket bound to the specified
-  address.
-
-* `UV_EADDRNOTAVAIL` The `address` parameter is an IP address that is not 
-
-* `UV_EINVAL` The server is already bound to an address.
-
-* `UV_EFAULT` Memory of `address` parameter is unintelligible.
-
-
-    int uv_listen(uv_tcp_server_t*, int backlog, uv_connection_cb cb);
-
-Begins listening for connections. The accept callback is level-triggered.
-
-
-    int uv_accept(uv_tcp_server_t* server,
-                  uv_tcp_t* client);
-
-Accepts a connection. This should be called after the accept callback is
-made. The `client` parameter should be uninitialized memory; `uv_accept` is
-used instead of `uv_tcp_init` for server-side `uv_tcp_t` initialization.
-
-Return value 0 indicates success, -1 failure. Possible errors:
-
-* `UV_EAGAIN` There are no connections. Wait for the `uv_connection_cb` callback
-  to be called again.
-
-* `UV_EFAULT` The memory of either `server` is unintelligible.
-
-
-
-# `uv_stream_t`
-
-An abstract subclass of `uv_handle_t`. Streams represent something that
-reads and/or writes data. Streams can be half or full-duplex. TCP sockets
-are streams, files are streams with offsets.
-
-    int uv_read_start(uv_stream_t* stream,
-                      uv_alloc_cb alloc_cb,
-                      uv_read_cb read_cb);
-
-Starts the stream reading continuously. The `alloc_cb` is used to allow the
-user to implement various means of supplying the stream with buffers to
-fill. The `read_cb` returns buffers to the user filled with data.
-
-Sometimes the buffers returned to the user do not contain data. This does
-not indicate EOF as in other systems. EOF is made via the `uv_eof_cb` which
-can be set like this `uv_set_eof_cb(stream, eof_cb);`
-
-
-    int uv_read_stop(uv_stream_t* stream);
-
-Stops reading from the stream.
-
-    int uv_write_req_init(uv_write_req_t*,

-                          int butcnf);
-
-Initiates a write request on a stream.
-
-    int uv_shutdown_req_init(uv_shutdown_req_t*, uv_stream_t*)
-
-Initiates a shutdown of outgoing data once the write queue drains.
-
-
-
-# `uv_tcp_t`
-
-The TCP handle class represents one endpoint of a duplex TCP stream.
-`uv_tcp_t` is a subclass of `uv_stream_t`. A TCP handle can represent a
-client side connection (one that has been used with uv_connect_req_init`)
-or a server-side connection (one that was initialized with `uv_accept`)
-
-    int uv_connect_req_init(uv_connect_req_t* req,
-                            uv_tcp_t* socket,
-                            struct sockaddr* addr);
-
-Initiates a request to open a connection.
-
-
-
-# `uv_req_t`
-
-Abstract class represents an asynchronous request. This is a subclass of `uv_handle_t`.
-
-
-# `uv_connect_req_t`
-
-Subclass of `uv_req_t`. Represents a request for a TCP connection. Operates
-on `uv_tcp_t` handles. Like other types of requests the `close_cb` indicates
-completion of the request.
-
-    int uv_connect_req_init(uv_connect_req_t* req,
-                            uv_tcp_t* socket,
-                            struct sockaddr* addr);
-
-Initializes the connection request. Returning 0 indicates success, -1 if
-there was an error. The following values can be retrieved from
-`uv_last_error` in the case of an error:
-
-* ???
-
-
-# `uv_shutdown_req_t`
-
-Subclass of `uv_req_t`. Represents an ongoing shutdown request. Once the
-write queue of the parent `uv_stream_t` is drained, the outbound data
-channel is shutdown. Once a shutdown request is initiated on a stream, the
-stream will allow no more writes.
-
-    int uv_shutdown_req_init(uv_shutdown_req_t*,
-                             uv_stream_t* parent);
-
-Initializes the shutdown request.
-
-
-# `uv_write_req_t`
-
-    int uv_write_req_init(uv_write_req_t*,
-                          uv_stream_t*,
-                          uv_buf_t bufs[],

-=head1 NAME
-
-libeio - truly asynchronous POSIX I/O
-
-=head1 SYNOPSIS
-
-  #include <eio.h>
-
-=head1 DESCRIPTION
-
-The newest version of this document is also available as an html-formatted
-web page you might find easier to navigate when reading it for the first
-time: L<http://pod.tst.eu/http://cvs.schmorp.de/libeio/eio.pod>.
-
-Note that this library is a by-product of the C<IO::AIO> perl
-module, and many of the subtler points regarding requets lifetime
-and so on are only documented in its documentation at the
-moment: L<http://pod.tst.eu/http://cvs.schmorp.de/IO-AIO/AIO.pm>.
-
-=head2 FEATURES
-
-This library provides fully asynchronous versions of most POSIX functions
-dealign with I/O. Unlike most asynchronous libraries, this not only
-includes C<read> and C<write>, but also C<open>, C<stat>, C<unlink> and
-similar functions, as well as less rarely ones such as C<mknod>, C<futime>
-or C<readlink>.
-
-It also offers wrappers around C<sendfile> (Solaris, Linux, HP-UX and
-FreeBSD, with emulation on other platforms) and C<readahead> (Linux, with
-emulation elsewhere>).
-
-The goal is to enable you to write fully non-blocking programs. For
-example, in a game server, you would not want to freeze for a few seconds
-just because the server is running a backup and you happen to call
-C<readdir>.
-
-=head2 TIME REPRESENTATION
-
-Libeio represents time as a single floating point number, representing the
-(fractional) number of seconds since the (POSIX) epoch (somewhere near
-the beginning of 1970, details are complicated, don't ask). This type is
-called C<eio_tstamp>, but it is guarenteed to be of type C<double> (or
-better), so you can freely use C<double> yourself.
-
-Unlike the name component C<stamp> might indicate, it is also used for
-time differences throughout libeio.
-
-=head2 FORK SUPPORT
-
-Calling C<fork ()> is fully supported by this module. It is implemented in these steps:
-
-   1. wait till all requests in "execute" state have been handled
-      (basically requests that are already handed over to the kernel).
-   2. fork
-   3. in the parent, continue business as usual, done
-   4. in the child, destroy all ready and pending requests and free the
-      memory used by the worker threads. This gives you a fully empty
-      libeio queue.
-
-=head1 INITIALISATION/INTEGRATION
-
-Before you can call any eio functions you first have to initialise the
-library. The library integrates into any event loop, but can also be used
-without one, including in polling mode.
-
-You have to provide the necessary glue yourself, however.
-
-=over 4
-
-=item int eio_init (void (*want_poll)(void), void (*done_poll)(void))
-
-This function initialises the library. On success it returns C<0>, on
-failure it returns C<-1> and sets C<errno> appropriately.
-
-It accepts two function pointers specifying callbacks as argument, both of
-which can be C<0>, in which case the callback isn't called.
-
-=item want_poll callback
-
-The C<want_poll> callback is invoked whenever libeio wants attention (i.e.
-it wants to be polled by calling C<eio_poll>). It is "edge-triggered",
-that is, it will only be called once when eio wants attention, until all
-pending requests have been handled.
-
-This callback is called while locks are being held, so I<you must
-not call any libeio functions inside this callback>. That includes
-C<eio_poll>. What you should do is notify some other thread, or wake up
-your event loop, and then call C<eio_poll>.
-
-=item done_poll callback
-
-This callback is invoked when libeio detects that all pending requests
-have been handled. It is "edge-triggered", that is, it will only be
-called once after C<want_poll>. To put it differently, C<want_poll> and
-C<done_poll> are invoked in pairs: after C<want_poll> you have to call
-C<eio_poll ()> until either C<eio_poll> indicates that everything has been
-handled or C<done_poll> has been called, which signals the same.
-
-Note that C<eio_poll> might return after C<done_poll> and C<want_poll>
-have been called again, so watch out for races in your code.
-
-As with C<want_poll>, this callback is called while lcoks are being held,
-so you I<must not call any libeio functions form within this callback>.
-
-=item int eio_poll ()
-
-This function has to be called whenever there are pending requests that
-need finishing. You usually call this after C<want_poll> has indicated
-that you should do so, but you can also call this function regularly to
-poll for new results.
-
-If any request invocation returns a non-zero value, then C<eio_poll ()>
-immediately returns with that value as return value.
-
-Otherwise, if all requests could be handled, it returns C<0>. If for some
-reason not all requests have been handled, i.e. some are still pending, it
-returns C<-1>.
-
-=back
-
-For libev, you would typically use an C<ev_async> watcher: the
-C<want_poll> callback would invoke C<ev_async_send> to wake up the event
-loop. Inside the callback set for the watcher, one would call C<eio_poll
-()> (followed by C<ev_async_send> again if C<eio_poll> indicates that not
-all requests have been handled yet). The race is taken care of because
-libev resets/rearms the async watcher before calling your callback,
-and therefore, before calling C<eio_poll>. This might result in (some)
-spurious wake-ups, but is generally harmless.
-
-For most other event loops, you would typically use a pipe - the event
-loop should be told to wait for read readyness on the read end. In
-C<want_poll> you would write a single byte, in C<done_poll> you would try
-to read that byte, and in the callback for the read end, you would call
-C<eio_poll>. The race is avoided here because the event loop should invoke
-your callback again and again until the byte has been read (as the pipe
-read callback does not read it, only C<done_poll>).
-
-=head2 CONFIGURATION
-
-The functions in this section can sometimes be useful, but the default
-configuration will do in most case, so you should skip this section on
-first reading.
-
-=over 4
-
-=item eio_set_max_poll_time (eio_tstamp nseconds)
-
-This causes C<eio_poll ()> to return after it has detected that it was
-running for C<nsecond> seconds or longer (this number can be fractional).
-
-This can be used to limit the amount of time spent handling eio requests,
-for example, in interactive programs, you might want to limit this time to
-C<0.01> seconds or so.
-
-Note that:
-
-a) libeio doesn't know how long your request callbacks take, so the time
-spent in C<eio_poll> is up to one callback invocation longer then this
-interval.
-
-b) this is implemented by calling C<gettimeofday> after each request,
-which can be costly.
-
-c) at least one request will be handled.
-
-=item eio_set_max_poll_reqs (unsigned int nreqs)
-
-When C<nreqs> is non-zero, then C<eio_poll> will not handle more than
-C<nreqs> requests per invocation. This is a less costly way to limit the
-amount of work done by C<eio_poll> then setting a time limit.
-
-If you know your callbacks are generally fast, you could use this to
-encourage interactiveness in your programs by setting it to C<10>, C<100>
-or even C<1000>.
-
-=item eio_set_min_parallel (unsigned int nthreads)
-
-Make sure libeio can handle at least this many requests in parallel. It
-might be able handle more.
-
-=item eio_set_max_parallel (unsigned int nthreads)
-
-Set the maximum number of threads that libeio will spawn.
-
-=item eio_set_max_idle (unsigned int nthreads)
-
-Libeio uses threads internally to handle most requests, and will start and stop threads on demand.
-
-This call can be used to limit the number of idle threads (threads without
-work to do): libeio will keep some threads idle in preperation for more
-requests, but never longer than C<nthreads> threads.
-
-In addition to this, libeio will also stop threads when they are idle for
-a few seconds, regardless of this setting.
-
-=item unsigned int eio_nthreads ()
-
-Return the number of worker threads currently running.
-
-=item unsigned int eio_nreqs ()
-
-Return the number of requests currently handled by libeio. This is the
-total number of requests that have been submitted to libeio, but not yet
-destroyed.
-
-=item unsigned int eio_nready ()
-
-Returns the number of ready requests, i.e. requests that have been
-submitted but have not yet entered the execution phase.
-
-=item unsigned int eio_npending ()
-
-Returns the number of pending requests, i.e. requests that have been
-executed and have results, but have not been finished yet by a call to
-C<eio_poll>).

-=head1 ANATOMY OF AN EIO REQUEST
-
-#TODO
-
-
-=head1 HIGH LEVEL REQUEST API
-
-#TODO
-
-=back
-
-
-=head1 LOW LEVEL REQUEST API
-
-#TODO
-
-=head1 EMBEDDING
-
-Libeio can be embedded directly into programs. This functionality is not
-documented and not (yet) officially supported.
-
-Note that, when including C<libeio.m4>, you are responsible for defining
-the compilation environment (C<_LARGEFILE_SOURCE>, C<_GNU_SOURCE> etc.).
-
-If you need to know how, check the C<IO::AIO> perl module, which does
-exactly that.
-
-
-=head1 COMPILETIME CONFIGURATION
-
-These symbols, if used, must be defined when compiling F<eio.c>.
-
-=over 4
-
-=item EIO_STACKSIZE
-
-This symbol governs the stack size for each eio thread. Libeio itself
-was written to use very little stackspace, but when using C<EIO_CUSTOM>
-requests, you might want to increase this.
-
-If this symbol is undefined (the default) then libeio will use its default
-stack size (C<sizeof (long) * 4096> currently).  If it is defined, but
-C<0>, then the default operating system stack size will be used. In all
-other cases, the value must be an expression that evaluates to the desired
-stack size.
-
-=back
-
-
-=head1 PORTABILITY REQUIREMENTS
-
-In addition to a working ISO-C implementation, libeio relies on a few
-additional extensions:
-
-=over 4
-
-=item POSIX threads
-
-To be portable, this module uses threads, specifically, the POSIX threads
-library must be available (and working, which partially excludes many xBSD
-systems, where C<fork ()> is buggy).
-
-=item POSIX-compatible filesystem API
-
-This is actually a harder portability requirement: The libeio API is quite
-demanding regarding POSIX API calls (symlinks, user/group management
-etc.).
-
-=item C<double> must hold a time value in seconds with enough accuracy
-
-The type C<double> is used to represent timestamps. It is required to
-have at least 51 bits of mantissa (and 9 bits of exponent), which is good
-enough for at least into the year 4000. This requirement is fulfilled by
-implementations implementing IEEE 754 (basically all existing ones).
-
-=back
-
-If you know of other additional requirements drop me a note.

+Revision history for libeio
+
+TODO: maybe add mincore support? available on at least darwin, solaris, linux, freebsd
+TODO: openbsd requires stdint.h for intptr_t - why posix?
+
+TODO: make mtouch/readdir maybe others cancellable in-request
+TODO: fadvise request
+1.0
+	- fix a deadlock where a wakeup signal could be missed when
+          a timeout occured at the same time.
+	- use nonstandard but maybe-working-on-bsd fork technique.
+        - use fewer time() syscalls when waiting for new requests.
+        - fix a path-memory-leak in readdir when using the wrappers
+          (reported by Thomas L. Shinnick).
+	- support a max_idle value of 0.
+	- support setting of idle timeout value (eio_set_idle_timeout).
+        - readdir: correctly handle malloc failures.
+        - readdir: new flags argument, can return inode
+          and possibly filetype, can sort in various ways.
+        - readdir: stop immediately when cancelled, do
+          not continue reading the directory.
+        - fix return value of eio_sendfile_sync.
+        - include sys/mman.h for msync.
+	- added EIO_STACKSIZE.
+	- added msync, mtouch support (untested).
+        - added sync_file_range (untested).
+        - fixed custom support.
+        - use a more robust feed-add detection method.
+	- "outbundled" from IO::AIO.
+        - eio_set_max_polltime did not properly convert time to ticks.
+        - tentatively support darwin in sendfile.
+        - fix freebsd/darwin sendfile.
+        - also use sendfile emulation for ENOTSUP and EOPNOTSUPP
+          error codes.
+        - add OS-independent EIO_MT_* and EIO_MS_* flag enums.
+        - add eio_statvfs/eio_fstatvfs.
+        - add eio_mlock/eio_mlockall and OS-independent MCL_* flag enums.
+        - no longer set errno to 0 before making syscalls, this only lures
+          people into the trap of believing errno shows success or failure.
+        - "fix" demo.c so that it works as non-root.
+        - suppoert utimes seperately from futimes, as some systems have
+          utimes but not futimes.
+        - use _POSIX_MEMLOCK_RANGE for mlock.
+        - do not (errornously) overwrite CFLAGS in configure.ac.
+        - mknod used int3 for dev_t (§2 bit), not offs (64 bit).
+        - fix memory corruption in eio_readdirx for the flags
+          combination EIO_READDIR_STAT_ORDER | EIO_READDIR_DIRS_FIRST.
+        - port to openbsd (another blatantly broken non-UNIX/POSIX platform).
+        - fix eio_custom prototype.
+        - work around a Linux (and likely FreeBSD and other kernels) bug
+          where sendfile would not transfer all the requested bytes on
+          large transfers, using a heuristic.
+        - use libecb, and apply lots of minor space optimisations.
+        - disable sendfile on darwin, broken as everything else.
+        - add realpath request and implementation.
+	- cancelled requests will still invoke their request callbacks.
+        - add fallocate.
+        - do not acquire any locks when forking.
+        - incorporated some mingw32 changes by traviscline.
+        - added syncfs support, using direct syscall.
+        - set thread name on linux (ps -L/Hcx, top, gdb).
+        - remove useless use of volatile variables.

+=head1 NAME
+
+libeio - truly asynchronous POSIX I/O
+
+=head1 SYNOPSIS
+
+  #include <eio.h>
+
+=head1 DESCRIPTION
+
+The newest version of this document is also available as an html-formatted
+web page you might find easier to navigate when reading it for the first
+time: L<http://pod.tst.eu/http://cvs.schmorp.de/libeio/eio.pod>.
+
+Note that this library is a by-product of the C<IO::AIO> perl
+module, and many of the subtler points regarding requests lifetime
+and so on are only documented in its documentation at the
+moment: L<http://pod.tst.eu/http://cvs.schmorp.de/IO-AIO/AIO.pm>.
+
+=head2 FEATURES
+
+This library provides fully asynchronous versions of most POSIX functions
+dealing with I/O. Unlike most asynchronous libraries, this not only
+includes C<read> and C<write>, but also C<open>, C<stat>, C<unlink> and
+similar functions, as well as less rarely ones such as C<mknod>, C<futime>
+or C<readlink>.
+
+It also offers wrappers around C<sendfile> (Solaris, Linux, HP-UX and
+FreeBSD, with emulation on other platforms) and C<readahead> (Linux, with
+emulation elsewhere>).
+
+The goal is to enable you to write fully non-blocking programs. For
+example, in a game server, you would not want to freeze for a few seconds
+just because the server is running a backup and you happen to call
+C<readdir>.
+
+=head2 TIME REPRESENTATION
+
+Libeio represents time as a single floating point number, representing the
+(fractional) number of seconds since the (POSIX) epoch (somewhere near
+the beginning of 1970, details are complicated, don't ask). This type is
+called C<eio_tstamp>, but it is guaranteed to be of type C<double> (or
+better), so you can freely use C<double> yourself.
+
+Unlike the name component C<stamp> might indicate, it is also used for
+time differences throughout libeio.
+
+=head2 FORK SUPPORT
+
+Usage of pthreads in a program changes the semantics of fork
+considerably. Specifically, only async-safe functions can be called after
+fork. Libeio uses pthreads, so this applies, and makes using fork hard for
+anything but relatively fork + exec uses.
+
+This library only works in the process that initialised it: Forking is
+fully supported, but using libeio in any other process than the one that
+called C<eio_init> is not.
+
+You might get around by not I<using> libeio before (or after) forking in
+the parent, and using it in the child afterwards. You could also try to
+call the L<eio_init> function again in the child, which will brutally
+reinitialise all data structures, which isn't POSIX conformant, but
+typically works.
+
+Otherwise, the only recommendation you should follow is: treat fork code
+the same way you treat signal handlers, and only ever call C<eio_init> in
+the process that uses it, and only once ever.
+
+=head1 INITIALISATION/INTEGRATION
+
+Before you can call any eio functions you first have to initialise the
+library. The library integrates into any event loop, but can also be used
+without one, including in polling mode.
+
+You have to provide the necessary glue yourself, however.
+
+=over 4
+
+=item int eio_init (void (*want_poll)(void), void (*done_poll)(void))
+
+This function initialises the library. On success it returns C<0>, on
+failure it returns C<-1> and sets C<errno> appropriately.
+
+It accepts two function pointers specifying callbacks as argument, both of
+which can be C<0>, in which case the callback isn't called.
+
+There is currently no way to change these callbacks later, or to
+"uninitialise" the library again.
+
+=item want_poll callback
+
+The C<want_poll> callback is invoked whenever libeio wants attention (i.e.
+it wants to be polled by calling C<eio_poll>). It is "edge-triggered",
+that is, it will only be called once when eio wants attention, until all
+pending requests have been handled.
+
+This callback is called while locks are being held, so I<you must
+not call any libeio functions inside this callback>. That includes
+C<eio_poll>. What you should do is notify some other thread, or wake up
+your event loop, and then call C<eio_poll>.
+
+=item done_poll callback
+
+This callback is invoked when libeio detects that all pending requests
+have been handled. It is "edge-triggered", that is, it will only be
+called once after C<want_poll>. To put it differently, C<want_poll> and
+C<done_poll> are invoked in pairs: after C<want_poll> you have to call
+C<eio_poll ()> until either C<eio_poll> indicates that everything has been
+handled or C<done_poll> has been called, which signals the same.
+
+Note that C<eio_poll> might return after C<done_poll> and C<want_poll>
+have been called again, so watch out for races in your code.
+
+As with C<want_poll>, this callback is called while locks are being held,
+so you I<must not call any libeio functions form within this callback>.
+
+=item int eio_poll ()
+
+This function has to be called whenever there are pending requests that
+need finishing. You usually call this after C<want_poll> has indicated
+that you should do so, but you can also call this function regularly to
+poll for new results.
+
+If any request invocation returns a non-zero value, then C<eio_poll ()>
+immediately returns with that value as return value.
+
+Otherwise, if all requests could be handled, it returns C<0>. If for some
+reason not all requests have been handled, i.e. some are still pending, it
+returns C<-1>.
+
+=back
+
+For libev, you would typically use an C<ev_async> watcher: the
+C<want_poll> callback would invoke C<ev_async_send> to wake up the event
+loop. Inside the callback set for the watcher, one would call C<eio_poll
+()>.
+
+If C<eio_poll ()> is configured to not handle all results in one go
+(i.e. it returns C<-1>) then you should start an idle watcher that calls
+C<eio_poll> until it returns something C<!= -1>.
+
+A full-featured connector between libeio and libev would look as follows
+(if C<eio_poll> is handling all requests, it can of course be simplified a
+lot by removing the idle watcher logic):
+
+  static struct ev_loop *loop;
+  static ev_idle repeat_watcher;
+  static ev_async ready_watcher;
+
+  /* idle watcher callback, only used when eio_poll */
+  /* didn't handle all results in one call */
+  static void
+  repeat (EV_P_ ev_idle *w, int revents)
+  {
+    if (eio_poll () != -1)
+      ev_idle_stop (EV_A_ w);
+  }
+
+  /* eio has some results, process them */
+  static void
+  ready (EV_P_ ev_async *w, int revents)
+  {
+    if (eio_poll () == -1)
+      ev_idle_start (EV_A_ &repeat_watcher);
+  }
+
+  /* wake up the event loop */
+  static void
+  want_poll (void)
+  {
+    ev_async_send (loop, &ready_watcher)
+  }
+
+  void
+  my_init_eio ()
+  {
+    loop = EV_DEFAULT;
+
+    ev_idle_init (&repeat_watcher, repeat);
+    ev_async_init (&ready_watcher, ready);
+    ev_async_start (loop &watcher);
+
+    eio_init (want_poll, 0);
+  }
+
+For most other event loops, you would typically use a pipe - the event
+loop should be told to wait for read readiness on the read end. In
+C<want_poll> you would write a single byte, in C<done_poll> you would try
+to read that byte, and in the callback for the read end, you would call
+C<eio_poll>.
+
+You don't have to take special care in the case C<eio_poll> doesn't handle
+all requests, as the done callback will not be invoked, so the event loop
+will still signal readiness for the pipe until I<all> results have been
+processed.

+Libeio has both a high-level API, which consists of calling a request
+function with a callback to be called on completion, and a low-level API
+where you fill out request structures and submit them.
+
+This section describes the high-level API.
+
+=head2 REQUEST SUBMISSION AND RESULT PROCESSING
+
+You submit a request by calling the relevant C<eio_TYPE> function with the
+required parameters, a callback of type C<int (*eio_cb)(eio_req *req)>
+(called C<eio_cb> below) and a freely usable C<void *data> argument.
+
+The return value will either be 0, in case something went really wrong
+(which can basically only happen on very fatal errors, such as C<malloc>
+returning 0, which is rather unlikely), or a pointer to the newly-created
+and submitted C<eio_req *>.
+
+The callback will be called with an C<eio_req *> which contains the
+results of the request. The members you can access inside that structure
+vary from request to request, except for:
+
+=over 4
+
+=item C<ssize_t result>
+
+This contains the result value from the call (usually the same as the
+syscall of the same name).
+
+=item C<int errorno>
+
+This contains the value of C<errno> after the call.
+
+=item C<void *data>
+
+The C<void *data> member simply stores the value of the C<data> argument.
+
+=back
+
+The return value of the callback is normally C<0>, which tells libeio to
+continue normally. If a callback returns a nonzero value, libeio will
+stop processing results (in C<eio_poll>) and will return the value to its
+caller.
+
+Memory areas passed to libeio must stay valid as long as a request
+executes, with the exception of paths, which are being copied
+internally. Any memory libeio itself allocates will be freed after the
+finish callback has been called. If you want to manage all memory passed
+to libeio yourself you can use the low-level API.
+
+For example, to open a file, you could do this:
+
+  static int
+  file_open_done (eio_req *req)
+  {
+    if (req->result < 0)
+      {
+        /* open() returned -1 */
+        errno = req->errorno;
+        perror ("open");
+      }
+    else
+      {
+        int fd = req->result;
+        /* now we have the new fd in fd */
+      }
+
+    return 0;
+  }
+
+  /* the first three arguments are passed to open(2) */
+  /* the remaining are priority, callback and data */
+  if (!eio_open ("/etc/passwd", O_RDONLY, 0, 0, file_open_done, 0))
+    abort (); /* something went wrong, we will all die!!! */
+
+Note that you additionally need to call C<eio_poll> when the C<want_cb>
+indicates that requests are ready to be processed.
+
+=head2 CANCELLING REQUESTS
+
+Sometimes the need for a request goes away before the request is
+finished. In that case, one can cancel the request by a call to
+C<eio_cancel>:
+
+=over 4
+
+=item eio_cancel (eio_req *req)
+
+Cancel the request (and all its subrequests). If the request is currently
+executing it might still continue to execute, and in other cases it might
+still take a while till the request is cancelled.
+
+Even if cancelled, the finish callback will still be invoked - the
+callbacks of all cancellable requests need to check whether the request
+has been cancelled by calling C<EIO_CANCELLED (req)>:
+
+  static int
+  my_eio_cb (eio_req *req)
+  {
+    if (EIO_CANCELLED (req))
+      return 0;
+  }
+
+In addition, cancelled requests will I<either> have C<< req->result >>
+set to C<-1> and C<errno> to C<ECANCELED>, or I<otherwise> they were
+successfully executed, despite being cancelled (e.g. when they have
+already been executed at the time they were cancelled).
+
+C<EIO_CANCELLED> is still true for requests that have successfully
+executed, as long as C<eio_cancel> was called on them at some point.
+
+=back
+
+=head2 AVAILABLE REQUESTS
+
+The following request functions are available. I<All> of them return the
+C<eio_req *> on success and C<0> on failure, and I<all> of them have the
+same three trailing arguments: C<pri>, C<cb> and C<data>. The C<cb> is
+mandatory, but in most cases, you pass in C<0> as C<pri> and C<0> or some
+custom data value as C<data>.
+
+=head3 POSIX API WRAPPERS
+
+These requests simply wrap the POSIX call of the same name, with the same
+arguments. If a function is not implemented by the OS and cannot be emulated
+in some way, then all of these return C<-1> and set C<errorno> to C<ENOSYS>.

+
+These two requests are called C<read> and C<write>, but actually wrap
+C<pread> and C<pwrite>. On systems that lack these calls (such as cygwin),
+libeio uses lseek/read_or_write/lseek and a mutex to serialise the
+requests, so all these requests run serially and do not disturb each
+other. However, they still disturb the file offset while they run, so it's
+not safe to call these functions concurrently with non-libeio functions on
+the same fd on these systems.
+
+Not surprisingly, pread and pwrite are not thread-safe on Darwin (OS/X),
+so it is advised not to submit multiple requests on the same fd on this
+horrible pile of garbage.
+
+=item eio_mlockall  (int flags, int pri, eio_cb cb, void *data)

+
+=item eio_readlink  (const char *path, int pri, eio_cb cb, void *data)
+
+If successful, the path read by C<readlink(2)> can be accessed via C<<

+=item eio_realpath  (const char *path, int pri, eio_cb cb, void *data)
+
+Similar to the realpath libc function, but unlike that one, C<<
+req->result >> is C<-1> on failure. On success, the result is the length
+of the returned path in C<ptr2> (which is I<NOT> 0-terminated) - this is
+similar to readlink.

+
+  EIO_STRUCT_STAT *statdata = (EIO_STRUCT_STAT *)req->ptr2;

+
+=head3 READING DIRECTORIES
+
+Reading directories sounds simple, but can be rather demanding, especially
+if you want to do stuff such as traversing a directory hierarchy or
+processing all files in a directory. Libeio can assist these complex tasks
+with it's C<eio_readdir> call.
+
+=over 4
+
+=item eio_readdir (const char *path, int flags, int pri, eio_cb cb, void *data)
+
+This is a very complex call. It basically reads through a whole directory
+(via the C<opendir>, C<readdir> and C<closedir> calls) and returns either
+the names or an array of C<struct eio_dirent>, depending on the C<flags>
+argument.
+
+The C<< req->result >> indicates either the number of files found, or
+C<-1> on error. On success, null-terminated names can be found as C<< req->ptr2 >>,
+and C<struct eio_dirents>, if requested by C<flags>, can be found via C<<
+req->ptr1 >>.
+
+Here is an example that prints all the names:
+
+  int i;
+  char *names = (char *)req->ptr2;
+
+  for (i = 0; i < req->result; ++i)
+    {
+      printf ("name #%d: %s\n", i, names);
+
+      /* move to next name */
+      names += strlen (names) + 1;
+    }
+
+Pseudo-entries such as F<.> and F<..> are never returned by C<eio_readdir>.
+
+C<flags> can be any combination of:
+
+=over 4
+
+=item EIO_READDIR_DENTS
+
+If this flag is specified, then, in addition to the names in C<ptr2>,
+also an array of C<struct eio_dirent> is returned, in C<ptr1>. A C<struct
+eio_dirent> looks like this:
+
+  struct eio_dirent
+  {
+    int nameofs; /* offset of null-terminated name string in (char *)req->ptr2 */
+    unsigned short namelen; /* size of filename without trailing 0 */
+    unsigned char type; /* one of EIO_DT_* */
+    signed char score; /* internal use */
+    ino_t inode; /* the inode number, if available, otherwise unspecified */
+  };
+
+The only members you normally would access are C<nameofs>, which is the
+byte-offset from C<ptr2> to the start of the name, C<namelen> and C<type>.
+
+C<type> can be one of:
+
+C<EIO_DT_UNKNOWN> - if the type is not known (very common) and you have to C<stat>
+the name yourself if you need to know,
+one of the "standard" POSIX file types (C<EIO_DT_REG>, C<EIO_DT_DIR>, C<EIO_DT_LNK>,
+C<EIO_DT_FIFO>, C<EIO_DT_SOCK>, C<EIO_DT_CHR>, C<EIO_DT_BLK>)
+or some OS-specific type (currently
+C<EIO_DT_MPC> - multiplexed char device (v7+coherent),
+C<EIO_DT_NAM> - xenix special named file,
+C<EIO_DT_MPB> - multiplexed block device (v7+coherent),
+C<EIO_DT_NWK> - HP-UX network special,
+C<EIO_DT_CMP> - VxFS compressed,
+C<EIO_DT_DOOR> - solaris door, or
+C<EIO_DT_WHT>).
+
+This example prints all names and their type:
+
+  int i;
+  struct eio_dirent *ents = (struct eio_dirent *)req->ptr1;
+  char *names = (char *)req->ptr2;
+
+  for (i = 0; i < req->result; ++i)
+    {
+      struct eio_dirent *ent = ents + i;
+      char *name = names + ent->nameofs;
+
+      printf ("name #%d: %s (type %d)\n", i, name, ent->type);
+    }
+
+=item EIO_READDIR_DIRS_FIRST
+
+When this flag is specified, then the names will be returned in an order
+where likely directories come first, in optimal C<stat> order. This is
+useful when you need to quickly find directories, or you want to find all
+directories while avoiding to stat() each entry.
+
+If the system returns type information in readdir, then this is used
+to find directories directly. Otherwise, likely directories are names
+beginning with ".", or otherwise names with no dots, of which names with
+short names are tried first.
+
+=item EIO_READDIR_STAT_ORDER
+
+When this flag is specified, then the names will be returned in an order
+suitable for stat()'ing each one. That is, when you plan to stat()
+all files in the given directory, then the returned order will likely
+be fastest.
+
+If both this flag and C<EIO_READDIR_DIRS_FIRST> are specified, then the
+likely directories come first, resulting in a less optimal stat order.
+
+=item EIO_READDIR_FOUND_UNKNOWN
+
+This flag should not be specified when calling C<eio_readdir>. Instead,
+it is being set by C<eio_readdir> (you can access the C<flags> via C<<
+req->int1 >>, when any of the C<type>'s found were C<EIO_DT_UNKNOWN>. The
+absence of this flag therefore indicates that all C<type>'s are known,
+which can be used to speed up some algorithms.
+
+A typical use case would be to identify all subdirectories within a
+directory - you would ask C<eio_readdir> for C<EIO_READDIR_DIRS_FIRST>. If
+then this flag is I<NOT> set, then all the entries at the beginning of the
+returned array of type C<EIO_DT_DIR> are the directories. Otherwise, you
+should start C<stat()>'ing the entries starting at the beginning of the
+array, stopping as soon as you found all directories (the count can be
+deduced by the link count of the directory).

+
+=head3 OS-SPECIFIC CALL WRAPPERS
+
+These wrap OS-specific calls (usually Linux ones), and might or might not
+be emulated on other operating systems. Calls that are not emulated will
+return C<-1> and set C<errno> to C<ENOSYS>.
+
+=over 4
+
+=item eio_sendfile (int out_fd, int in_fd, off_t in_offset, size_t length, int pri, eio_cb cb, void *data)
+
+Wraps the C<sendfile> syscall. The arguments follow the Linux version, but
+libeio supports and will use similar calls on FreeBSD, HP/UX, Solaris and
+Darwin.
+
+If the OS doesn't support some sendfile-like call, or the call fails,
+indicating support for the given file descriptor type (for example,
+Linux's sendfile might not support file to file copies), then libeio will
+emulate the call in userspace, so there are almost no limitations on its
+use.
+
+=item eio_readahead (int fd, off_t offset, size_t length, int pri, eio_cb cb, void *data)
+
+Calls C<readahead(2)>. If the syscall is missing, then the call is
+emulated by simply reading the data (currently in 64kiB chunks).
+
+=item eio_syncfs (int fd, int pri, eio_cb cb, void *data)
+
+Calls Linux' C<syncfs> syscall, if available. Returns C<-1> and sets
+C<errno> to C<ENOSYS> if the call is missing I<but still calls sync()>,
+if the C<fd> is C<< >= 0 >>, so you can probe for the availability of the
+syscall with a negative C<fd> argument and checking for C<-1/ENOSYS>.
+
+=item eio_sync_file_range (int fd, off_t offset, size_t nbytes, unsigned int flags, int pri, eio_cb cb, void *data)
+
+Calls C<sync_file_range>. If the syscall is missing, then this is the same
+as calling C<fdatasync>.
+
+Flags can be any combination of C<EIO_SYNC_FILE_RANGE_WAIT_BEFORE>,
+C<EIO_SYNC_FILE_RANGE_WRITE> and C<EIO_SYNC_FILE_RANGE_WAIT_AFTER>.
+
+=item eio_fallocate (int fd, int mode, off_t offset, off_t len, int pri, eio_cb cb, void *data)
+
+Calls C<fallocate> (note: I<NOT> C<posix_fallocate>!). If the syscall is
+missing, then it returns failure and sets C<errno> to C<ENOSYS>.
+
+The C<mode> argument can be C<0> (for behaviour similar to
+C<posix_fallocate>), or C<EIO_FALLOC_FL_KEEP_SIZE>, which keeps the size
+of the file unchanged (but still preallocates space beyond end of file).
+
+=back
+
+=head3 LIBEIO-SPECIFIC REQUESTS
+
+These requests are specific to libeio and do not correspond to any OS call.
+
+=over 4
+
+=item eio_mtouch (void *addr, size_t length, int flags, int pri, eio_cb cb, void *data)
+
+Reads (C<flags == 0>) or modifies (C<flags == EIO_MT_MODIFY) the given
+memory area, page-wise, that is, it reads (or reads and writes back) the
+first octet of every page that spans the memory area.
+
+This can be used to page in some mmapped file, or dirty some pages. Note
+that dirtying is an unlocked read-write access, so races can ensue when
+the some other thread modifies the data stored in that memory area.
+
+=item eio_custom (void (*)(eio_req *) execute, int pri, eio_cb cb, void *data)
+
+Executes a custom request, i.e., a user-specified callback.
+
+The callback gets the C<eio_req *> as parameter and is expected to read
+and modify any request-specific members. Specifically, it should set C<<
+req->result >> to the result value, just like other requests.
+
+Here is an example that simply calls C<open>, like C<eio_open>, but it
+uses the C<data> member as filename and uses a hardcoded C<O_RDONLY>. If
+you want to pass more/other parameters, you either need to pass some
+struct or so via C<data> or provide your own wrapper using the low-level
+API.
+
+  static int
+  my_open_done (eio_req *req)

+
+  eio_custom (my_open, 0, my_open_done, "/etc/passwd");
+
+=item eio_busy (eio_tstamp delay, int pri, eio_cb cb, void *data)
+
+This is a request that takes C<delay> seconds to execute, but otherwise
+does nothing - it simply puts one of the worker threads to sleep for this
+long.
+
+This request can be used to artificially increase load, e.g. for debugging
+or benchmarking reasons.
+
+=item eio_nop (int pri, eio_cb cb, void *data)
+   
+This request does nothing, except go through the whole request cycle. This
+can be used to measure latency or in some cases to simplify code, but is
+not really of much use.
+
+=back
+
+=head3 GROUPING AND LIMITING REQUESTS
+
+There is one more rather special request, C<eio_grp>. It is a very special
+aio request: Instead of doing something, it is a container for other eio
+requests.
+
+There are two primary use cases for this: a) bundle many requests into a
+single, composite, request with a definite callback and the ability to
+cancel the whole request with its subrequests and b) limiting the number
+of "active" requests.
+
+Further below you will find more discussion of these topics - first
+follows the reference section detailing the request generator and other
+methods.
+
+=over 4
+
+=item eio_req *grp = eio_grp (eio_cb cb, void *data)
+
+Creates, submits and returns a group request. Note that it doesn't have a
+priority, unlike all other requests.
+
+=item eio_grp_add (eio_req *grp, eio_req *req)
+
+Adds a request to the request group.
+
+=item eio_grp_cancel (eio_req *grp)
+
+Cancels all requests I<in> the group, but I<not> the group request
+itself. You can cancel the group request I<and> all subrequests via a
+normal C<eio_cancel> call.
+
+=back
+
+=head4 GROUP REQUEST LIFETIME
+
+Left alone, a group request will instantly move to the pending state and
+will be finished at the next call of C<eio_poll>.
+
+The usefulness stems from the fact that, if a subrequest is added to a
+group I<before> a call to C<eio_poll>, via C<eio_grp_add>, then the group
+will not finish until all the subrequests have finished.
+
+So the usage cycle of a group request is like this: after it is created,
+you normally instantly add a subrequest. If none is added, the group
+request will finish on it's own. As long as subrequests are added before
+the group request is finished it will be kept from finishing, that is the
+callbacks of any subrequests can, in turn, add more requests to the group,
+and as long as any requests are active, the group request itself will not
+finish.
+
+=head4 CREATING COMPOSITE REQUESTS
+
+Imagine you wanted to create an C<eio_load> request that opens a file,
+reads it and closes it. This means it has to execute at least three eio
+requests, but for various reasons it might be nice if that request looked
+like any other eio request.
+
+This can be done with groups:
+
+=over 4
+
+=item 1) create the request object
+
+Create a group that contains all further requests. This is the request you
+can return as "the load request".
+
+=item 2) open the file, maybe
+
+Next, open the file with C<eio_open> and add the request to the group
+request and you are finished setting up the request.
+
+If, for some reason, you cannot C<eio_open> (path is a null ptr?) you
+can set C<< grp->result >> to C<-1> to signal an error and let the group
+request finish on its own.
+
+=item 3) open callback adds more requests
+
+In the open callback, if the open was not successful, copy C<<
+req->errorno >> to C<< grp->errorno >> and set C<< grp->errorno >> to
+C<-1> to signal an error.
+
+Otherwise, malloc some memory or so and issue a read request, adding the
+read request to the group.
+
+=item 4) continue issuing requests till finished
+
+In the real callback, check for errors and possibly continue with
+C<eio_close> or any other eio request in the same way.
+
+As soon as no new requests are added the group request will finish. Make
+sure you I<always> set C<< grp->result >> to some sensible value.

+This causes C<eio_poll ()> to return after it has detected that it was
+running for C<nsecond> seconds or longer (this number can be fractional).
+
+This can be used to limit the amount of time spent handling eio requests,
+for example, in interactive programs, you might want to limit this time to
+C<0.01> seconds or so.
+
+Note that:
+
+=over 4
+
+=item a) libeio doesn't know how long your request callbacks take, so the
+time spent in C<eio_poll> is up to one callback invocation longer then
+this interval.
+
+=item b) this is implemented by calling C<gettimeofday> after each
+request, which can be costly.
+
+=item c) at least one request will be handled.
+
+=back
+
+=item eio_set_max_poll_reqs (unsigned int nreqs)
+
+When C<nreqs> is non-zero, then C<eio_poll> will not handle more than
+C<nreqs> requests per invocation. This is a less costly way to limit the
+amount of work done by C<eio_poll> then setting a time limit.
+
+If you know your callbacks are generally fast, you could use this to
+encourage interactiveness in your programs by setting it to C<10>, C<100>
+or even C<1000>.
+
+=item eio_set_min_parallel (unsigned int nthreads)
+
+Make sure libeio can handle at least this many requests in parallel. It
+might be able handle more.
+
+=item eio_set_max_parallel (unsigned int nthreads)
+
+Set the maximum number of threads that libeio will spawn.
+
+=item eio_set_max_idle (unsigned int nthreads)
+
+Libeio uses threads internally to handle most requests, and will start and stop threads on demand.
+
+This call can be used to limit the number of idle threads (threads without
+work to do): libeio will keep some threads idle in preparation for more
+requests, but never longer than C<nthreads> threads.
+
+In addition to this, libeio will also stop threads when they are idle for
+a few seconds, regardless of this setting.
+
+=item unsigned int eio_nthreads ()
+
+Return the number of worker threads currently running.
+
+=item unsigned int eio_nreqs ()
+
+Return the number of requests currently handled by libeio. This is the
+total number of requests that have been submitted to libeio, but not yet
+destroyed.
+
+=item unsigned int eio_nready ()
+
+Returns the number of ready requests, i.e. requests that have been
+submitted but have not yet entered the execution phase.
+
+=item unsigned int eio_npending ()
+
+Returns the number of pending requests, i.e. requests that have been
+executed and have results, but have not been finished yet by a call to
+C<eio_poll>).
+
+=back
+
+=head1 EMBEDDING
+
+Libeio can be embedded directly into programs. This functionality is not
+documented and not (yet) officially supported.
+
+Note that, when including C<libeio.m4>, you are responsible for defining
+the compilation environment (C<_LARGEFILE_SOURCE>, C<_GNU_SOURCE> etc.).
+
+If you need to know how, check the C<IO::AIO> perl module, which does
+exactly that.
+
+
+=head1 COMPILETIME CONFIGURATION
+
+These symbols, if used, must be defined when compiling F<eio.c>.
+
+=over 4
+
+=item EIO_STACKSIZE
+
+This symbol governs the stack size for each eio thread. Libeio itself
+was written to use very little stackspace, but when using C<EIO_CUSTOM>
+requests, you might want to increase this.
+
+If this symbol is undefined (the default) then libeio will use its default
+stack size (C<sizeof (void *) * 4096> currently). If it is defined, but
+C<0>, then the default operating system stack size will be used. In all
+other cases, the value must be an expression that evaluates to the desired
+stack size.
+
+=back
+
+
+=head1 PORTABILITY REQUIREMENTS
+
+In addition to a working ISO-C implementation, libeio relies on a few
+additional extensions:
+
+=over 4
+
+=item POSIX threads
+
+To be portable, this module uses threads, specifically, the POSIX threads
+library must be available (and working, which partially excludes many xBSD
+systems, where C<fork ()> is buggy).
+
+=item POSIX-compatible filesystem API
+
+This is actually a harder portability requirement: The libeio API is quite
+demanding regarding POSIX API calls (symlinks, user/group management
+etc.).
+
+=item C<double> must hold a time value in seconds with enough accuracy
+
+The type C<double> is used to represent timestamps. It is required to
+have at least 51 bits of mantissa (and 9 bits of exponent), which is good
+enough for at least into the year 4000. This requirement is fulfilled by
+implementations implementing IEEE 754 (basically all existing ones).
+
+=back
+
+If you know of other additional requirements drop me a note.
