--- Comment #8 from Robbert van der Helm mail@robbertvanderhelm.nl --- I can confirm that this patch also resolves the issue in the situation where I initially encountered it, namely launching and subsequently trying to kill Winelib processes (https://github.com/robbert-vdh/yabridge/blob/b7a13652e910c1956677d296be69575...). I have not yet done any further testing beyond that though.
