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. -- Robin Becker -- http://mail.python.org/mailman/listinfo/python-list
