This can be done, as it is in loadlib.c and liolib.c. It requires that the
C function that is doing the lua_replace has its own lua stack (i.e. has
been lua_call()ed). I do not understand why.

So we see that the io. functions and package.loaders run in an
environment installed with lua_replace. (However, I dont understand
why the loaders do this).
