Previously an empty result list was accidentallly returned, since the

and of course found nothing.

bpo-30635: Fix refleak in test_c_locale_coercion (#2126)
When checking for reference leaks, test_c_locale_coercion is run
multiple times and so _LocaleCoercionTargetsTestCase.setUpClass() is
called multiple times. setUpClass() appends new value at each call,
so it looks like a reference leak.
Moving the setup from setUpClass() to setUpModule() avoids
this, eliminating the false alarm.
Don't run Python in an empty environment, but copy the current
environment and set PYTHONIOENCODING. So the test works also on
Python compiled in shared mode (using libpython).

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.

bpo-30266: support "= None" pattern in AbstractContextManager (#1448)
contextlib.AbstractContextManager now supports anti-registration
by setting __enter__ = None or __exit__ = None, following the pattern
introduced in bpo-25958.
* Add a new option taking a filename to get a list of test names to
filter tests.
* support.match_tests becomes a list.
* Modify run_unittest() to accept to match the whole test identifier,
not just a part of a test identifier.
For example, the following command only runs test_default_timeout()
of the BarrierTests class of test_threading:
$ ./python -m test -v test_threading -m test.test_threading.BarrierTests.test_default_timeout

Fix a reference in subinterpreters, like test_callbacks_leak() of
test_atexit.
warnoptions is a list used to pass options from the command line to
the sys module constructor. Before this change, the list was shared
by multiple interpreter which is not the expected behaviour. Each
interpreter should have their own independent mutable world.
This change duplicates the list in each interpreter. So each
interpreter owns its own list, so each interpreter can clear its own
list.
