Parallel(?) programming with python

[Andreas Croci]

I would like to thank everybody who answered my question. The insight 
was very informative. This seems to be one of the few newsgroups still 
alive and kicking, with a lot of knowledgeable people taking the time to 
help others. I like how quick and easy it is to post questions and 
receive answers here as compared to web-based forums (although there are 
some disadvantages too).

I'm implementing some of the ideas received here and I will surely have 
other questions as I go. But the project will take a long time because 
I'm doing this as a hobby during my vacation, that are unfortunately 
about to end.

Thanks again, Community.
