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.

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.

The public names (Thread, Condition, etc.) used to be factory functions

subclass extension types.
It is now possible to inherit from Thread and other classes, without
having to import the private underscored names like multiprocessing did.
A doc update will follow: a patch is under discussion on the issue.
