Thanks for the report. Atomic copy (`list(self.processes.values()`) should fix the bug, sure. I doubt if writing a reliable test for this situation is possible; multithreading is hard. I think we can accept a patch without a test but with an inline comment that describes why copy is crucial. ---------- versions: +Python 3.11 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue43498> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
