Disregard my 2nd email: I managed to wrangle up a repro case outside of my 

Not sure if it is completely minimal, but it does repro the conditions in my 
program that cause the failure. Also, I reproduced the bug as zmq::poll() 
having (revents & ZMQ_POLLIN) set following by a recv() hang, not a 
ZMQ_RCVMORE followed by recv() block. But, same difference, I think.
