The direction of the pipeline is now pretty clear, using PUSH/PULL.
That's fine.  But we all make mistakes when we write code...

The main lesson here seems to be that 0MQ will have to do pattern
verification so that it catches errors like this.

I.e. in the protocol, the connecting socket has to tell the other peer
what type it is, so the endpoint can reject illegal connections and
the caller can be told about it.
