[zeromq-dev] message loss at high send rate in Jyre

It might be a Jyre issue yet the most likely seems an issue in your
test case (the loss is so dramatic). What I'd do is simplify it, and
see when it starts happening.

If you are able to write a JNI layer then we could eventually wrap the
Zyre C API in Java.
