One way would be to maintain a Queue.Queue containing the messages that 
need to be sent and, rather than sleeping to retry just retrying when 
enough time has elapsed. That way you can keep pumping messages and so 
on to your heart's content, though you will have to keep track of the 
messages still to be sent.
