Cool.  Yes, GMP is very highly optimized, both in terms of using fancy
specialized algorithms for the modexp (e.g. Montgomery reduction), and
in using carefully tuned assembly code to get max performance from the
machine arithmetic.  I didn't even mention GMP in my post because
there's no way to expect a pure Forth implementation to come anywhere
near it.  I just wanted to know whether the Forth version was fast
enough to be useful at all, which it is.
