I suspect this would be a matter of personal taste, but I would say this is
too high level for libzmq - as you clarify in the guide, to do this reliably
you need some form of heartbeat, and I would say that this is something that
should be dealt with on the application layer. However, it does seem an
interesting idea for zapi - this could fairly easily be implemented as
pseudosockets on top of existing ones using the work already in the guide.
