title: How to use Tornado with a thread pool?
body: <p>I am coming from Java background and absolutely new at Python. </p>
  
  <p>I need to write a simple web server to handle multiple concurrent requests. The request processing is mostly CPU bound and handling a single request may take 100 - 1000 ms. The server will run on a multicore machine.</p>
  
  <p>I was advised to use <code>Tornado</code> with a thread pool. Do you have any example ?</p>
