[zeromq-dev] DEALER<->DEALER, do both ends connect?

[Pieter Hintjens]

One end binds, one end connects. If you do both, it will partially
work, and create two pipes between the sockets, that is, two TCP
connections. The results will be weird. You'll get messages swapping
order randomly. Connect one, bind the other, and it'll work as you
expect.
