By the way, I fixed various issues to ensure that ResourceWarning are
displayed at Python exit. There are still corner cases when the
warnings are not emited. For example, when a daemon thread is used. Or
when the warning comes very late during Python finalization.

Recent example of tricky issue related to this warning: #22898. IMO
it's a bug, it must be fixed and it should be possible to emit the
warning.
