title: Using python and Azure Topics, is it possible to use long polling
body: <p>I am trying to access Azure ServiceBus Topics using python.  From what I've been reading, I can access this using AMQP and proton-python.</p>
  
  <p>In the .net world, there is the concept of long-polling, where you wait for a message to arrive.</p>
  
  <p>Is such a concept available using AMQP and python?</p>
