title: Tornado request timeouts
body: <p>I have a Tornado Web application which connects to an external app server on a TCP port on localhost. Sometimes, if the app server responds slowly, then even requests to the Tornado server which do not talk to the app server become slow as they are held up for the other requests to finish. What's the right way to handle this?</p>
  
  <p>Thanks,
  Ashish</p>
