* gh-93353: Fix importlib.resources._tempfile() finalizer (GH-93377)Miss Islington (bot)2022-06-131-2/+5
| | | | | | | | Fix the importlib.resources.as_file() context manager to remove the temporary file if destroyed late during Python finalization: keep a local reference to the os.remove() function. Patch by Victor Stinner. (cherry picked from commit 443ca731d6b1267fe2f92985e0490460c95e44a8) Co-authored-by: Victor Stinner <vstinner@python.org>

| | | | | | | Confirmed with @jaraco that this indeed needs a fix. A question that came up while I was digging into the code: I think `SelectableGroups` could similarly use `__slots__ = ()`, since its purpose seems only for convenience around `dict`, not to have attributes of its own.
