Issue 30154 that I've marked as a duplicate demonstrates this problem without using shell=True. The solution I proposed handles that via the additional small timeout on the cleanup side, but still has the caveat that the grandchild processes keep running unless the caller used start_new_session=True. See the PR. We cannot reasonably determine when start_new_session=True should be a default behavior. And I worry that doing it when it should not be will cause unexpected new problems with existing code.
