I see you are using erlang:trace for that. Neat! Ultimately I don't 
think we'll go that route for high-churn stats like message counts, 
since tracing is probably not sufficiently efficient for that. And, as 
you say, it is brittle w.r.t. broker API changes. But until we have 
baked better stats gathering into the broker core, erlang:trace is hard 
to beat in terms of concision and non-intrusiveness.
