…eceiving events

The watcher might be cleared on thread stop but the C callback would still send events.
Let's ignore them to prevent unhandled exceptions later:

    AttributeError: 'NoneType' object has no attribute 'is_recursive'
      File "watchdog/observers/fsevents.py", line 299, in callback
        emitter.queue_events(emitter.timeout, events)
      File "watchdog/observers/fsevents.py", line 261, in queue_events
        self._queue_created_event(event, src_path, src_dirname)
      File "watchdog/observers/fsevents.py", line 124, in _queue_created_event
        self.queue_event(DirModifiedEvent(dirname))
      File "watchdog/observers/fsevents.py", line 97, in queue_event
        if self._watch.is_recursive :

Or even:

    AttributeError: 'NoneType' object has no attribute 'path'
      File "watchdog/observers/fsevents.py", line 299, in callback
        emitter.queue_events(emitter.timeout, events)
      File "watchdog/observers/fsevents.py", line 174, in queue_events
        src_path = self._encode_path(event.path)
      File "watchdog/observers/fsevents.py", line 323, in _encode_path
        if isinstance(self.watch.path, bytes):
