Good proposal!
Additionally I was also considering tracking windowed average of NIT 
processing time (request to response), food for thought.
I'm also after a mechanism to report NIT elapsed time to the TU somehow.
The NIT proc time could (should) be an RRD style object. That would 
permit fairly useful stats to be gathered.
