Great.

I think we should put warning notes in the appropriate place in the code
regarding this (if not already there now), as this is one feature that at first blush
seems appropriate
for optimizing by an unsuspecting programmer, in the future.

The last thing we want is this "feature" to creep back in a few years from now when
none of us are vigilant about this.
