Well I think the reference is clear on that point: ZMQ does not provide any
synchronisation for sockets. It does provide synchronisation for contexts.

Also worth noting: people writing multi-threaded network applications are
typically not average website designers, I wouldn't underestimate their
expertise. Even with 0MQ some of the applications are pretty hairy :)
