R functions can call libraries written in other languages, and can start 
processes, etc.  R doesn't know everything going on in every function 
call, and would have a lot of trouble saving it.

If you added some limitations, e.g. a process that periodically has its 
entire state stored in R variables, then it would be a lot easier.
