Sorry Fred to be bringing you the bad news. You must have been hiding
under a hole for a few years if you weren't aware of the bad news: Python
is not terribly good at parallel computing in a shared-memory model. To
achieve good parallel computing, you need to use several process, like
does the processing module that Robert mentioned.

This issue has been mentioned on the scipy-user mailing list more than
once.

Cheers,

Gaël
