Nick Coghlan <ncogh...@gmail.com> added the comment: The main idea that comes to mind is to cache a reference to `_frozen_importlib._module_locks` in the interpreter state, and do a key lookup in there (since any in-progress import should have a lock allocated to it).
That would be a separate performance issue though - for this issue, we're on an error handling path, so the speed with which the error gets reported isn't critical (although it does technically slow down try/except import fallback chains). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue33237> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
