I do a similar thing by using the globals table. I load all the
functionality I want and then save a reference in C to the globals. then I
install a empty globals table (making the old one inaccessible from Lua) and
do a *shallow* copy of all the entries from the saved state to the new
globals. Then after running scripts that could corrupt the state I reset by
installing a new globals table and doing a shallow copy to it.
Doesn't solve the general problem of course but it works for all non-table
globals. And is faster than recreating the original state.
