OK.  Do you think it's a problem in Jyre or JeroMQ?

So here's a C test case that does this:
https://gist.github.com/hintjens/d54d25c30e0339fb0a87

I do get message loss if I (a) start broadcasting before all nodes are ready or (b) don't wait for all messages to return. Otherwise it works even with no pause between message sends.
