    @knusbaum Yeah, agreed. I was seeing larger view, but when we narrow the 
view, this PR would be add a tiny amount of load. Seeing is believing so I 
would like to see performance test result.

> I envision being able to browse the Storm UI and see where queues of tuples 
> are backing up.
> Today if I see latencies increasing at a bolt, it may not be due to anything 
> specific to that bolt, but that it is backed up behind an overwhelmed bolt 
> (which has too low of parallelism or too high of latency).
> I would expect this could use sampling like the metrics reported to the UI 
> today, and just retrieve data from netty about the state of the queues. I 
> wouldn't imagine supporting zeromq on the first pass.
