Structure of Lua (In C)

[Olivier Hamel <evilpineapple@...>]

Now before I start confusing myself past what I already am (medication 
isn't helping), I'd like someone to confirm that the following 
description of how Lua's data structures are built internally and that 
I'm not going insane.

(Just check the src again to make sure, and now I'm certain I'm going 
insane. Probably will become as clear as day once someone actually 
explains it...)

Create a new state -> Returns a lua_State structure
With that state you also created indirectly a global_State structure 
which holds the 'real' state (the one all 'threads' share)
Create a new coroutine ('thread', why can't we use the same 
terminology?) spawns a new lua_State and makes it point to the 
global_State that it's parent points to.

So lua_State is more of a coroutine instance and global_State holds all 
the real meat of that Lua universe. Now all I need to figure out is what 
the LG structure does. (No bloody clue. It seems to be some sort of 
marker to specify the size of an empty global state and one lua state. 
Right?)

Thanks for any clarification,
Olivier
