I started testing this and started to run into some issues.
I created a new test, but the test is crap, because it takes way too long
to run, but does give some good results.
https://github.com/apache/storm/compare/master...revans2:stats-test?expand=1
I plan to expand this more, but for now I am running into the following
exception.
```
