I haven't thought about it in detail yet. But in general, my plan is to 
change KJS to be iterative instead of recursive. This way, the current 
execution state will be explicitly represented, rather than implicitly 
by the C stack. That way you  can save the state and resume execution 
at the same point.

This will most likely involve a lot of changes in kjs/nodes.cpp and 
hardly any changes anywhere else.

I haven't really thought through it in a lot of detail yet.
