Of course, there's the tiny little chance that I unknowingly
fixed some obscure bug in the process of rewriting, and that it
was that bug that accounted for the overhead...  (:

It would be interesting to see if anyone could verify (or refute)
my theory that CPS-transformation can actually yield significant
speedups (they don't have to be in the order of 9000x to be
significant.)
