On: ZeroMQ instead of HTTP, for internal services

I'm curious, did you have some sort of timeout mechanic for your REP sockets? I don't, but I've never had problems either because I don't have that much traffic.

AFAIK ZeroMQ doesn't support any kind of timeout on REP sockets. It could be hacked in with signals or a watchdog thread in a multiprocessing setup, but that's ugly. If you're going to all that trouble it seems much cleaner to just move to DEALER/ROUTER.

I do like the way REQ/REP keeps track of the requests and has RPC semantics, though. Instead of blocking, you could always poll and time out instead.
