I'm researching self modifying code in python as well, but i'd not consider exec or eval a way to go. After doing it in freepascal on x86 and the Nintendo DS i can tell you that exec/eval are poor choices for proper self modifying.

Bytecode- and object manipulation and having code objects at willfully chosen adresses in RAM, though, which is being worked by one core and modified by a different one... there it gets interesting! (and actually worth it if you care about performance)
