Standard POSIX fork semantics should be a guidance. IIUC, termination of the last thread is equivalent to calling exit(0) (although return from main() still means that exit is invoked right away, and the return value of main is the exit code - right?). Calling exit means to call all exit handlers. So to match POSIX semantics, we should also call the exit handlers in the child process (along with invoking a final garbage collection etc.) Regards, Martin _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
