This article is relatively old (2006) and pretty outdated. I can't find the link now, but I remember reading that Stackless is no longer recommended, because modern Python can now provide the same functionality (using generators).

If you can stick with regular Python then I highly recommend it; Stackless requires a different Python binary with is a PITA for deployment/production.

I understand that generators allow concurrency, but not parallelism (you can't have more than one generator actually running at the same time, on different cores).

If Stackless doesn't support parallelism either (I have no clue), then yeah, it doesn't make much sense to use it.

Yep, yep. Stackless doesn't support parallelism either, it only enables cooperative multitasking.
