I see that you are unregistering, closing the socket, and then immediately creating a new socket with the same IDENTITY. 

I did not see any code setting the LINGER option to drop packets, so if a late packet arrives I suppose it could cause that zmq_close() to hang. 

Alternately, reusing the IDENTITY before the socket is completely closed (an async operation) may be a cause. Any chance you can close the socket and then schedule (within your loop) the creation of a replacement socket a few milliseconds later?

These are just two guesses based on 5m review of the code. I hope it sparks an idea or a new avenue to pursue.
