[New-bugs-announce] [issue44974] Warning about "Unknown child process pid" in test_asyncio

[Serhiy Storchaka]

New submission from Serhiy Storchaka <storchaka+cpython at gmail.com>:

Ryan Mast reported about a warning about "Unknown child process pid" after finishing test_asyncio (see msg400018 and https://github.com/python/cpython/pull/27870#issuecomment-903072119 for details).

I cannot reproduce it locally. Ryan, could you help with locating the source of this warning? First suspect is test_close_dont_kill_finished. If it is not, it may be other test calling kill().
