Moreover, test_huge_content_recvinto() seems to change the event loop policy without restoring it once done:

@vstinner This issue has not been happening on the CI recently so can this be marked as pending or even close it and reopen when it does fail?
msg414430 - (view) Author: STINNER Victor (vstinner) * (Python committer) Date: 2022-03-03 11:27
I didn't see this failure recently, I just close the issue.
