title: Google AppEngine libraries import
body: <p>I'm currently looking around to find what's allow and what's not in GAE.</p>
  
  <p>Using the <a href="https://developers.google.com" rel="nofollow">Google's Developers website</a>, I found that _socket C Libraries and the socket module are not allowed on GAE.</p>
  
  <p>How did they disable these modules? Did they performed a complete rebuild of the python interpreter or did they developed their own (like pypy)?</p>
