Note that the RATE limits what is forwarded onto the wire, not what you are
feeding into 0mq.  If you send fast enough with no high watermark you will
consume a significant amount of memory to adverse affects.  An application
rate limited is recommended but may be more suitable as an optional layer
above 0mq API.
