I took that to mean they have those two low-level native methods
(probably declared as protected or private), and implement all the
high-level methods (such as the ones I listed for 0MQ) by calling those
two. This would make sense to me (#1).

It also makes sense (in an OO world) to NOT use the "Socket" word; these
are socket objects anyway, so we should have setHWM() and getRate()
(#2).

Finally, if we go this way I would like to deprecate (or simply
eliminate) the two setsockopt() methods and all the socket option
constants that are declared in ZMQ.java (#3).

This is my current "formal" proposal (#1, #2 and #3). More thoughts?
