[zeromq-dev] EPGM PUB/SUB leak?

[Matteo Fortini]

I tried with 3.2.3 and it's funny how I simply cannot get the
subscriber to unblock on epgm, while it works with a tcp:// socket
instead. The code is the same, I tried both zsocket_connect and
zsocket_bind on both sides, no luck (of course with tcp:// the config
that works is bind()ing on the publisher and connect()ing on the
subscriber.

I'll try master next, but this puzzles me.
