This is doing a round-trip, right?

That becomes slow. There's a lot of latency for pushing single
messages through the whole stack like this.

It's perhaps the main problem with the current libzmq design; too much
happens for one message. It's fine when you send streams of data but
it gets slow when you do round trips.
