This is a very, very good point -- and something I already really missed 
some times!  I think I found some efforts to implement a very simple 
statistical profiler some years ago on the internet once, but it seems 
there's currently no work being done or plans to implement one?

Are there any technical problems associated with it, or is it "simply 
not done yet"?  At least to me, this really seems like both a (possibly) 
interesting as well as very useful project.

Yours,
Daniel
