* Add a private _block_on_close attribute to ForkingMixIn and
ThreadingMixIn classes of socketserver.
* Use _block_on_close=True in test_socketserver and test_logging
* bpo-31234: Add test.support.wait_threads_exit() (GH-3578)
Use _thread.count() to wait until threads exit. The new context
manager prevents the "dangling thread" warning.
(cherry picked from commit ff40ecda73)
* bpo-31234: Try to fix lock_tests warning (#3557)
Try to fix the "Warning -- threading_cleanup() failed to cleanup 1
threads" warning in test.lock_tests: wait a little bit longer to give
time to the threads to complete.
Warning seen on test_thread and test_importlib.
(cherry picked from commit 096ae3373a)
* bpo-31479: Always reset the signal alarm in tests
Use "try: ... finally: signal.signal(0)" pattern to make sure that
tests don't "leak" a pending fatal signal alarm.
* Move two more alarm() calls into the try block
Fix also typo: replace signal.signal(0) with signal.alarm(0)
* Move another signal.alarm() into the try block
(cherry picked from commit 9abee722d4)
* Move fd_count() from test.libregrtest.refleak to test.support
* Fix support.fd_count() on Windows: Call CrtSetReportMode() to not
kill the process on invalid file descriptor if Python is compiled
in debug mode.
When an unawaited coroutine is collected very late in shutdown --
like, during the final GC at the end of PyImport_Cleanup -- then it
was triggering an interpreter abort, because we'd try to look up the
"warnings" module and not only was it missing (we were prepared for
that), but the entire module system was missing (which we were not
prepared for).
I've tried to fix this at the source, by making the utility function
get_warnings_attr robust against this in general. Note that it already
has the convention that it can return NULL without setting an error,
which is how it signals that the attribute it was asked to fetch is
missing, and that all callers already check for NULL returns.
There's a similar check for being late in shutdown at the top of
warn_explicit, which might be unnecessary after this fix, but I'm not
sure so I'm going to leave it..

Fix test_ignore() of multiprocessing tests like
test_multiprocessing_forkserver: use support.PIPE_MAX_SIZE to make
sure that send_bytes() blocks.
(cherry picked from commit 5d6c7ed5e3)
* Add a space to ensurepip's --altinstall option
* Add periods to the arguments of ensurepip that didn't have it
This makes --help for all optional arguments consistent and also makes it
consistent with pip --help.

Fix a race condition in SSLProtocol.connection_made() of
asyncio.sslproto: start immediately the handshake instead of using
call_soon(). Previously, data_received() could be called before the
handshake started, causing the handshake to hang or fail.

Fixed bug where calling write_eof() on a _SelectorSocketTransport after
it's already closed raises AttributeError.

* Typo fix spotted by Guido
The proactor event loop has a race condition when reading with
pausing/resuming. `resume_reading()` unconditionally schedules the read
function to read from the current future. If `resume_reading()` was
called before the previously scheduled done callback fires, this results
in two attempts to get the data from the most recent read and an
assertion failure. This commit tracks whether or not `resume_reading`
needs to reschedule the callback to restart the loop, preventing a
second attempt to read the data..

* Fixed a leak when the GC fails to add an object with __del__ into
the gc.garbage list.
* PyGC_Collect() can now be called when an exception is set and
preserves it.
* Fixed an undefined behavior with comparing a dead pointer with NULL.

uuid._ipconfig_getnode did not validate the maximum length of the value,
so long as the value had the same type of formatting as a MAC address.
This let it select DUIDs as MAC addresses. It now requires an exact
length match.

* bpo-33263 Fix FD leak in _SelectorSocketTransport. (GH-6450)
Under particular circumstances _SelectorSocketTransport can try to add a reader
even the transport is already being closed. This can lead to FD leak and
invalid stated of the following connections. Fixed the SelectorSocketTransport
to add the reader only if the trasport is still active..
