title: How to read all message from queue using stomp library in Python?
body: <p>How can I read all messages from stomp queue in Python?</p>
  
  <p>I wrote such code but it reads only one message and exists - how to force read all messages.</p>

      conn.set_listener('message', ConnectionListener(conn))
