Heh, yes, it does. I've read up on setjmp/longjmp, it's just how
they're used by Lua that's a bit beyond me.

Well, I put exactly that after lua_call in the hook function; as I
said before, that was the second thing I tried. (Except that I can't
return the return value of lua_yield, the hook returns void, I just
left off the "return", but it's the last thing the function does.) And
it seemed to never go back to the coroutine, it just re-executed the
hook function every time I resumed.

Ah, I didn't realize that. It's not really documented anywhere, is it?
