title: Python Threads (or their equivalent) on Google Application Engine Workaround?
body: <p>I want to make a Google App Engine app that does the following: </p>
  
  <ol>
  <li>Client makes an asynchronous http request</li>
  <li>Server starts processing that request</li>
  <li>Client makes ajax http requests to get progress</li>
  </ol>
  
  <p>The problem is that the server processing (step #2) may take more than 30 seconds.</p>
  
  <p>I know that you can't have threads on Google Application Engine and that all tasks must complete within 30 seconds or they get shut down. Is there some way to work around this?</p>
  
  <p>Also, I'm using python-django as a backend.</p>
