LocalStore::addTempRoot(): Handle ENOENT If the garbage collector has acquired the global GC lock, but hasn't created the GC socket yet, then a client attempting to connect would get ENOENT. Note that this only happens when the GC runs for the first time on a machine. Subsequently clients will get ECONNREFUSED which was already handled. Fixes #7370. 2023-06-19 14:54:05 +00:00			`fifo2=$TEST_ROOT/test2.fifo`
