[Stackless] Event-based scheduling

[Phoenix Sol]

I'm always amazed at how *more educated* programmers complain that Stackless
is
confusing or difficult to adapt to. It seems so simple and elegant to my
*self-educated*
mind. I'm feeling rather happy right now to be ignorant of traditional
threads, semaphores, etc...

Thanks for that, Laurent!  =)

(Now if I could just find a job... ;-)
