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

See on AMD64 Fedora Rawhide Refleaks 3.x:
https://buildbot.python.org/all/#/builders/82/builds/7

I found the leaking test using test.bisect_cmd:

$ ./python -m test test_asyncio -R 3:3 --fail-env-changed -v -m test.test_asyncio.test_subprocess.SubprocessPidfdWatcherTests.test_close_dont_kill_finished
...
test_asyncio leaked [1, 1, 1] file descriptors, sum=3
