Something along these lines was already proposed in BugZilla#186[1], and
the it is something we want to do, indeed. It should be possible to
reset either all or only selected stats. Similarly, we could make it
possible to completely remove said stat counter, not just reset it.

This is something I'd like to see in 3.4, isn't too hard to do, either
as far as I see, so there's hope!
