For purposes of computational parallelism (more my background than Guido's -- the idea that you might want to use a thread to avoid blocking on I/O was novel to me <wink>), the global interpreter lock renders Python useless except for prototyping, so there's not much point digging into the hundreds of higher-level parallelism models that have been developed.
Well, maybe. I'm still hoping to prove you at least partly wrong one of these years. ;-)
(The long-term plan for my BCD module is to turn it into a C extension that releases the GIL. If that's successful, I'll start working on ways to have Numeric release the GIL.)
