Thank you for reply. I found similar info in MacOSX doc. (in CAVEATS) http://developer.apple.com/documentation/Darwin/Reference/ManPages/man2/fork.2.html I encountered this crash while investigating python's trunk/Lib/test/test_threading.py ThreadJoinOnShutdown (test_3_join_in_forked_from_thread) which hangs on cygwin. It's calling thread stuff and IO on child process, maybe it's not good practice... -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
