Richard Oudkerk b1694cf588 Issue #18999: Make multiprocessing use context objects.
This allows different parts of a program to use different methods for
starting processes without interfering with each other.

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.

Antoine Pitrou dd69649660 Issue #9205: concurrent.futures.ProcessPoolExecutor now detects killed
children and raises BrokenProcessPool in such a situation.  Previously it
would reliably freeze/deadlock.
