Back when I worked at IronPort, we had a proprietary implementation of
Stackless that I liked.  Christian Tismer worked there too at one
point.  Slide has one that is similar.  Our version of Stackless
worked with my open source Web application framework, Aquarium, and I
liked it a lot.  (By the way, I use Pylons these days because it
reminds me a lot of Aquarium, but with a larger community.)

Has anyone tried out out Eventlet?  It was written by Donnovan Preston
who worked at Slide and also wrote Nevow (the popular Web framework
for Twisted).

I've heard Concurrence is another similar framework.

I hope you won't mind if I link to my article on Python concurrency
(based on a talk that Alec and Libor from Slide helped me with):
