Interesting.  I hadn't heard of it, but I knew about GNU mp, the
multiple precision library.  CLISP uses the GNU mp library, which is
how it is so fast for a byte-compiled implementation, but it blew up
on the large bignums for some reason.

My wild-assed guess is that the CMUCL run (using bignums) was around
15 minutes (on a 2.8GHz P4).

On my 1GHz P3, the calc (apcalc on Debian, btw) run took 28 minutes
(24m22.203s user).  On what hardware did it take under 3 minutes?
