Nobody seems to have mentioned POSH http://poshmodule.sourceforge.net
which used almost to work. I assume it's busted for later pythons and the author 
says it's just a demonstration.

Anandtech demoed an 8 core mac pro machine and were unable to "max out the 
cpus". Python needs some kind of multi cpu magic pretty quickly or we'll all end 
up using erlang :)

As for subprocess I don't see it as much use unless we can at least determine 
the number of cpu's and also set the cpu affinity easy with occam maybe not in 
python.
