When exiting, the state's `is_initialized` flag is unset. Noticeable on Windows, when a thread tried to access the state's `exit_event` property to check whether it had been set, it would complain that the state was no longer initialized. Now, even when no longer initialized, if the `exit_event` is set, it will not raise an error when accessing this attribute.
