[zeromq-dev] ZMQ_XPUB_NODROP and zmq_proxy()

[Francesco]

Btw, just in case it can be useful to others:

I ended up setting ZMQ_XPUB_NODROP=1 on all sockets (both the INPROC PUB
ones attached to proxy frontend and the TCP PUB proxy backend socket) and
so far it works just fine: the PUB automatically adapts to the speed of the
slowest subscriber, and no messages are lost.
