[zeromq-dev] Paranoid Pirate pattern with priority queuing

[Hoobajoob Chef]

The requirement would just be: if there are multiple pending requests of differing priority, pending higher priority requests will always get delivered by the queue proxy to workers before pending lower priority requests.
I think this can be done in the queue proxy with per-priority endpoints on the frontend and a single backend endpoint for the workers at the cost of some additional enveloping work in the queue proxy so that worker responses can be sent back over the correct priority-specific frontend sockets.
