I have an N-cpu version of quicksort. It speeds up nicely on my dual-core
machine. Would some kind soul with a more-than-two processor machine be
willing to compile and run it for comparison?

I have a dual dual-core 64 bit machine (dual AMD Opteron). Where can I
get the code?

Here are 5 different runs, for statistical purposes. Compiled with
gnatmake -O3.
Let me know if you want me to try other switches.
