[zeromq-dev] Is it possible to get deadlocks in ZeroMQ applications?

[Timothee Besset]

I've also had deadlock cases where two threads would use several zmq
sockets to communicate with each other (for instance with both a REP/REQ
and a PAIR)

It's easy in those cases to have deadlocks, unless you use a poll to wait
on all of them at the same time.
