Yeah, basically. Thanks for looking over the patch, though. I have a
pretty clear idea of what's necessary now to make this work properly
(as opposed to hoping I get lucky and the lua_State is still useable).

I think wrapping the call to luaD_call in lua_call with a try/catch
block should be sufficient. The catch block could then handle error
recovery in roughly the same way as luaD_pcall, and create
lua_exceptions at that point, rather than in luaD_throw (removing the
extra string copies with lua_pcall). I'd have to make the LUAI_TRY
macro a little more complicated to handle the changes, but I'm
confident that I can avoid future problems.

Thanks again,
James
