Some of these tests were flaky since we could kill the process in some way without cleaning up the ProcessGroup. This resulted in issues where the FileStore didn't clean up appropriately resulting in other processes in the group to crash. Fixed this by explicitly deleting the process_group before we bring a process down forcibly.
