Actually, that brings up a more general question: what's with the
enthusiasm for clearing statistics *at all*?  ISTM that's something
you should do only in dire emergencies, like the collector went
haywire and has now got a bunch of garbage numbers.  The notion of
resetting subsets of the stats seems even more dubious, because now
you have numbers that aren't mutually comparable.  So I fail to
understand why the desire to expend valuable development time on
any of this.
