This will not actually prevent all queuing, just remove buffering in
ZeroMQ. You'll still get buffering in TCP and on the network itself.

If you want to remove all queuing completely, you have to switch to a
synchronous REQ/REP model, which is nasty. Better, use a credit based
flow control system to manage precisely the total amount of buffering.
