Reentrant calls and concurrent calls are not the same. If the import lock is changed to raise an exception, heaps of multi-threaded software will be broken. What we could do is set a timeout on the import lock, but then we need to choose a rather large one (e.g. 5 minutes), and who will wait 5 minutes before killing the process? ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue10923> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
