Probably ... the question is to what.
The default of 10 was chosen in our usual spirit of conservatism ---
and IIRC it was replacing code that tracked only *one* most common
value, so it was already a factor of 10 better (and more expensive)
than what was there before. But subsequent history suggests it's
too small. I'm not sure I want to vote for another 10x increase by
default, though.
