I only want to move
struct Table *mt[LUA_NUMTAGS]; /* metatables for basic types */
That seems like a bad idea: a value that is accessed via multiple
coroutines (or passed via resume/yield, or in a function that is called
from multiple coroutines) would get/loose its metatable depending on
where it is used.
and
TValue l_registry;
out of the global_State and into the lua_State.
And then `io.open` wouldn't find its metatable when called from within a
coroutine, C libraries would be loaded and gc'd multiple times, etc. ...
