Bug Description
Using eventlet.green.zmq consumes 100% CPU on writable sockets as it attempts to use a pattern for level-triggered interrupts with ZeroMQ's edge-triggered events. There is an upstream bug filed, yet unresolved. However, there is a patch that addresses the issue. The patch rewrites eventlet.green.zmq.
