All unit tests passed. All exposure works as expected. Extensive load testing has been done on FB's internal branch.

> One of the features that our DBAs use for MySQL analysis is "show processlist", which gives application-level stats about the RPC threads. Right now, we use jstack but that is very core-developer-centric. We need to create a similar tool that DBA/Ops/AppDevs can use.
