These tests spawn a thread that waits on a threading.Event. If the test fails any of its assertions, the Event won't be signaled and the thread will wait indefinitely, causing a deadlock when threading._shutdown() tries to join all outstanding threads.Co-authored-by: Brett Simmers <bsimmers@meta.com>

These tests spawn a thread that waits on a
threading.Event. If the test fails any of its assertions, theEventwon't be signaled and the thread will wait indefinitely, causing a deadlock whenthreading._shutdown()tries to join all outstanding threads.The solution is just to put the code in a
try-finallyblock, with the existing clean-up in thefinally.@swtaarrs found and fixed this originally while working onCinder.
Hopefully this is trivial enough to not need an issue or a NEWS blurb.
