New submission from STINNER Victor <vstinner at python.org>:

Warning seen o AMD64 Ubuntu Shared 3.x buildbot:
https://buildbot.python.org/all/#/builders/141/builds/2593

test_devnull_output (test.test_a=syncio.test_subprocess.SubprocessThreadedWatcherTests) ...
Warning -- threading_cleanup() failed to cleanup 1 threads (count: 1, dangling: 2)

The ThreadedChildWatcher class of asyncio.unix_events doesn't seem to have a method to join all threads. It should be done in tests to prevent "leaking" threads which can have side effects on following tests.
