I'm not sure that this counts as a bug.

Each non-daemon thread adds a lock to the threading._shutdown_locks set: https://github.com/python/cpython/blob/8b795ab5541d8a4e69be4137dfdc207714270b77/Lib/threading.py#L933-L935.

That lock is removed when the thread is "join"ed: https://github.com/python/cpython/blob/8b795ab5541d8a4e69be4137dfdc207714270b77/Lib/threading.py#L988-L990

So the simple solution is to make sure that you always join your threads (which I'd expect normal code to do for non-daemon threads anyway), or to make your threads daemon threads.
