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.

ed4a8fc095 Issue #8184: multiprocessing: On Windows, don't set SO_REUSEADDR on Connection 
sockets, and set FILE_FLAG_FIRST_PIPE_INSTANCE on named pipes, to make sure two
listeners can't bind to the same socket/pipe (or any existing socket/pipe).
