title: threading=True with flask-socketio
body: <p>I have been using flask, and some of my route handlers start computations that can take several minutes to complete. Using flask's development server, I can use app.run(threaded=True) and my server will continue to respond to other requests while it's off performing these multi-minute computation. </p>
  
  <p>Now I've starting using Flask-SocketIO and I'm not sure how to do the equivalent thing. I understand that I can explicitly spawn a separate thread in python any time it starts one of these computations. Is that the only way to do it? Or is there something equivalent to threaded=True for flask-socketio. (Or, more likely, am I just utterly confused.)</p>
  
  <p>Thanks for any help.</p>
