* Remove binding of captured exceptions when not used to reduce the chances of ↵Pablo Galindo2019-11-191-1/+1
| | | | | | | creating cycles (GH-17246) Capturing exceptions into names can lead to reference cycles though the __traceback__ attribute of the exceptions in some obscure cases that have been reported previously and fixed individually. As these variables are not used anyway, we can remove the binding to reduce the chances of creating reference cycles. See for example GH-13135

* bpo-31804: Fix multiprocessing.Process with broken standard streams (#6079)Antoine Pitrou2018-03-111-8/+1
| | | | | In some conditions the standard streams will be None or closed in the child process (for example if using "pythonw" instead of "python" on Windows). Avoid failing with a non-0 exit code in those conditions. Report and initial patch by poxthegreat.
