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.
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).
as (~0U) on NetBSD which was causing it to appear as -1 when used as
a signed int for _multprocessing.SemLock.SEM_VALUE_MAX. This works
around the problem by substituting INT_MAX on systems where it appears
negative when used as an int.

Issue #7272: Add configure test to detect whether sem_open works
properly, and use this to skip test_multiprocessing on platforms
where sem_open raises a signal. This should fix some FreeBSD buildbot
failures for test_multiprocessing.

Issue #7272, continued: don't re-use existing HAVE_BROKEN_POSIX_SEMAPHORES
to indicate that semaphores aren't available; define a new variable
POSIX_SEMAPHORES_NOT_ENABLED instead.
