A child process would inherit as many fds as the number of still-running children.

* Add blurb and test comment

Victor Stinner 3b69d911c5 bpo-30886: Fix multiprocessing.Queue.join_thread() (#2642) 
multiprocessing.Queue.join_thread() now waits until the thread
completes, even if the thread was started by the same process which
created the queue.

Fix the following warning which occurs randomly when running
test_handle_called_with_mp_queue of test_logging.QueueListenerTest:

Warning -- threading_cleanup() failed to cleanup -1 threads after 4 sec (count: 0, dangling: 1)

Antoine Pitrou 2b5cc5ebaf bpo-30643: Fix race condition in signal wakeup in forkserver (followup to PR #1989) (#2139) 
* Fix race condition in signal wakeup in forkserver (followup to PR #1989)

There's an admittedly well-known race condition where ECHILD can arrive
just before the C function epoll_wait() and the latter wouldn't therefore
return EINTR.  The solution is to use set_wakeup_fd(), which was designed
to avoid such race conditions.

* Reset wakeup fd in child

silently ignored.
