Whoops, I forgot about that, or I would have just grabbed it... from a
cursory look, it seems it may have better error messages, but
otherwise is very similar.  Both routines seem to work the same way.

The one thing I might change in Eli's code would be to use lua_concat
to prepend the underscore to the function name (instead of malloc).
That way there are no conflicts if somebody changes the lua allocation
routines.  Or else, use the dynamically sized array trick that's in
the code I posted -- since this is very platform-specific code, that
doesn't seem dangerous.

I don't have an OSX machine, but the luacheia project is set up to use
the sourceforge compile-farm to compile luacheia on lots of platforms
(including OSX) and run self-tests, so I can drop Eli's code into
luacheia and see what happens...
