Thanks for the response. My question is how to I get the coroutine's Lua 
state? What I gather from your response is that when run_ruby() is called, 
the lua_State passed to it is the main thread.

Do I have to create the thread using coco's lua_newcthread() and use it's 
returned Lua State? The documentation also states I can call 
'coroutine.create' from C so would the following:

    lua_getglobal(L, "coroutine");
    lua_getfield(L, -1, "create");
    lua_call(L, 1, ...);

work? If not, what do you mean?

Thanks a lot,
mitchell
