title: Lazy Pirate pattern with real request data
body: <p>I am learning zmq with PyZMQ binding and i have trouble with Lazy Pirate pattern.
  So, here is a code for <a href="http://zguide.zeromq.org/py%3alpserver" rel="nofollow">Lazy Pirate server</a> and <a href="http://zguide.zeromq.org/py%3alpclient" rel="nofollow">Lazy Pirate client</a>.</p>
  
  <p>In example client sends request, but it is simple number. How can i make a real request with text data and keep pattern realization?</p>
  
  <p>Also, i don't trully understand <code>sequence</code> variable in client code - it is incrementing infinitely => won't python crash when <code>sequence</code> reaches int variable maximum?</p>
