[zeromq-dev] Question about ZMQ_PAIR

True, we do not have the concept of "experimental" any longer in
ZeroMQ and this text should be changed. PAIR sockets are used in
production and therefore are a stable part of the API. Do you want to
make a PR to change this? (What remains accurate is that they're
incomplete and should only be used for inproc work).

((Perhaps someone will one day make a patch reimplementing PAIR as a
special case of DEALER, that should be simple and end this fuzziness))
