fc7b0ec5a2 Use setUpClass() and tearDownClass() in test_multiprocessing. 
Each manager test class now uses a separate manager.  Also, process
pools are no longer created before starting any tests.

Note that warnings are written if the manager for a test case still
has live objects when it is shutdown.  This is true for a few test cases
which fail to wait for all child processes to end.

59d5404bc7 Issue #14753: Make multiprocessing treat negative timeouts as it did in 3.2 
In Python 3.2 and earlier, Process.join() and Connection.poll()
treated negative timeouts as zero timeouts.  Earlier versions from
the 3.3 line of development treat them as infinite timeouts.

The patch reverts to the old behaviour.

225cb8d077 Make test_multiprocessing cleanup properly 
Previously, when an error was encountered some processes would not be
stopped until atexit callbacks were run.  On Windows that was too late
to prevent a PermissionError when regrtest tried to remove the temp
directory it ran the tests in.

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
