The issue was triggered without threads.If the __eq__ method of the objects used for keys use C functions releasing the GIL, you may trigger the issue. > Would it be worth adding a counter to lookdict, so that one modification is > OK, but 5 aren't? If you implement a special type modifying the dict that contains the object, you should implement your own retry function on lookup failure (catch RuntimeError). Honestly, if you get RuntimeError, you should change your program, not retry the lookup! ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue14205> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
