Hi Alex,

perhaps comprehensive system accounting (CSA) is a starter to see what  
ideas are already around for everyday's system accounting (for such long  
runners as Seaside).

In any case I think that accounting for memory and cpu should be per  
process (and so I would see my favorite memory integral again :) but that  
would require changes to ObjectMemory (object instantiation + GC) ...

Into quite another direction goes the polymorphism metrics, which  
addresses the actual receiver and/or target method per call site, and can  
serve as a measurement of an application's object-orientedness, etc. This  
should also be per process (or, better perhaps per ClassBox).

Hope that's not too much ;)
