_multiprocessing Connection methods don't check if handle is valid or not. If you close the socket/pipe, Python may crash on operations, especially in poll() on FD_SET(...handle, &rdfs). Example of crash: ---------------------- import _multiprocessing obj = _multiprocessing.Connection(755) obj.close() obj.poll() ---------------------- Attached patch is a proposition of fix to check handle in all Connection methods using the handle.
