[zeromq-dev] zmq_ipc

[Andrew Hume]

ooooh, i forgot the only diagnostic information i've discovered.

if i kill and then restart the sending process, things remain wedged.
if i kill and restart combinations of teh receiving processes, things remain wedged.
if i kill all teh receiving processes, and then restart them, things unwedge.

this is what makes me think this is a zmq issue.
