Before changing the const signatures I would say we should make it clear 
what constant zmq_msg_t means.

Keep in mind that zmq_msg_t is a BLOB descriptor rather than BLOB 
itself. In other words, several zmq_msg_t's can point to the same 
physical BLOB.

So, does const zmq_msg_t mean that the descriptor is constant or rather 
that the BLOB itself is constant?
