The original bug was for segmentation faults, which I'm not sure is happening anymore. At some point, the tests did work for me on Fedora 17 and I was unable to reproduce this bug.
Unfortunately, Eventlet's green.zmq had been effectively rewritten in the Folsom timeframe. In fact, I just submitted a pull request to green.zmq to fix one bug resulting from that... I suspect there are more.
