Antoine Pitrou bdb1cf1ca5 Issue #12328 : Fix multiprocessing's use of overlapped I/O on Windows. Also, add a multiprocessing.connection.wait(rlist, timeout=None) function for polling multiple objects at once. Patch by sbt. Complete changelist from sbt's patch: * Adds a wait(rlist, timeout=None) function for polling multiple objects at once. On Unix this is just a wrapper for select(rlist, [], [], timeout=None). * Removes use of the SentinelReady exception and the sentinels argument to certain methods. concurrent.futures.process has been changed to use wait() instead of SentinelReady. * Fixes bugs concerning PipeConnection.poll() and messages of zero length. * Fixes PipeListener.accept() to call ConnectNamedPipe() with overlapped=True. * Fixes Queue.empty() and SimpleQueue.empty() so that they are threadsafe on Windows. * Now PipeConnection.poll() and wait() will not modify the pipe except possibly by consuming a zero length message. (Previously poll() could consume a partial message.) * All of multiprocesing's pipe related blocking functions/methods are now interruptible by SIGINT on Windows.		14 years ago
