[zeromq-dev] send msq from pyzmq to a server that "wait's" with zsock_brecv()

[Luca Boccassi]

zsock_[b][recv|send] are designed and documented to be used just by
themselves. While it is possible (and simple) to reverse-engineer the
protocol (just look at the code in czmq/src/zsock.c), and it's also
very unlikely to ever change in an incompatible way at the network
level, we make no guarantees of this.
CZMQ has ffi python bindings that you can use as an alternative.
