I've been planning to pitch the idea to C python people that iterators be made picklable in vanilla python.
It seems like a perfectly reasonable extension to the language, and I'm sure the stackless python people would be willing to share some of the experience from stackless to make it happen.
The tricky part, which stackless has done, is to make generators picklable.
