   Hey! Just to chime in here: I like the idea of throwing an exception there 
and it seems fairly straightforward.
   
   To restart the heartbeat thread, is it sufficient to do that on the top of 
the consumer.poll()? I'm basically wondering if we could piggyback the restart 
onto the next user poll?
