For what it's worth, I'm aware that these statements somewhat
contradict each other.  Maybe we don't win as much from atomization
as we think, although I suspect there may be performance benefits
derived from code size reductions (since a single word comparison is
smaller than a function call or an inlined strcmp).  Or maybe
string comparisons succeeding quickly is important too.  (But
failing quickly is still *more* important.)
