Twisted has some feature like that implemented using pickles or some thing. It meant to save the state of the program during restart. I am not sure if that's what you are after. http://twistedmatrix.com

Actually, the Twisted developers also found this to be a terrible idea, and doesn't really do it any more. I definitely understand the appeal of such a system, but it has far too many problems to work well in Python, and even in Smalltalk (which was built from the start to work like this) it was the source of a number of long-term systematic problems with the ecosystem.
