title: python watchdog hang flask socketio
body: <p>I am using flask/flask socketio / rq. I need to run heavy tasks, so I am using rq.
  Everything works fine.</p>
  <p>the result of the task is a file and I want to track it changes. for that, I used a watchdog.
  The problem is when I install watchdog socketio is not accepting incoming requests anymore.</p>
  <p>what could be a problem? is usage watchdog is supported by socketio?</p>
