multiprocessing module

[makobu]

I have a function that makes two subprocess.Popen() calls on a file.

I have 8 cores. I need 8 instances of that function running in
parallel at any given time till all the files are worked on.
Can the multiprocessing module do this? If so, whats the best method?

A technical overview of how the multiprocessing module actually works
would also be really helpful.
