A good point, but would that really be required?
If lua_State "locks down" and does nothing on most API calls, returns  
nil/0 to every lua_topointer/touserdata, etc.
then most of the C code wouldn't need to know about it, unless it uses Lua  
calls to do C side resource management.

If there are may external modules, that would be Bad, yes. But if Lua is  
simply an embedded extension language, then this is not an issue.
