The simplest way to do this right-out-of-the-box is to use the registry.

You can also recompile Lua with a suitable definition of LUA_USERSTATE.
Lua will then allocate states in a block with two parts:
	
		| LUA_USERSTATE | Lua state |

and so you can backup the lua_State pointer to access your LUA_USERSTATE.
