On my 1.8GHz AMD64 in 32-bit mode with SBCL 0.9.3 I'm now getting:

5.21 seconds of real time
4.15 seconds of user run time
0.62 seconds of system run time
0 page faults and
509,569,248 bytes consed

This seems to be on-par with other people's observations.

This compares to 1.037s for OCaml and 0.987s for C++, so SBCL is now much
more competitive.

Thanks for all the help!
