Bug report
in test_asyncio.test_unix_events.PolicyTest.test_get_default_child_watcher, unix_events.can_use_pidfd is mocked within the test body, but never restored to the original function.
this doesn't cause test failures during regular test runs, but during a refleak test run on MacOS it a AttributeError: module 'os' has no attribute 'pidfd_open' to be thrown (presumably due to another test using the non-mocked function in the second iteration).
repro:
./python.exe -m test test_asyncio -m '*.test_unix_events.*' -R 2:2
WARNING: Running tests with --huntrleaks/-R and less than 3 warmup repetitions can give false positives!

this can be fixed by patching instead of mocking in the test_get_default_child_watcher test (PR coming up).
