An Athlon.  (As soon as I reload my Blade, I'll test it on the UltraSparc, 
also.  My Forte license expired while I was in San Diego, so it'll have to 
be gcc on there too, for now.)

I'll also rework my code generator and the logic to ramp it up to four or 
five hundred opcodes, which would be a little better test, I think.  
Anything else I should add or tweak?
