Comment 7 for bug 587597

I haven't tried to apply/compile that patch yet, but will do so. Also, worth being aware that Lua 5.2 is coming along - see http://www.corsix.org/content/look-lua-52-work3 for changes. Shouldn't have a major effect, but probably the Lua implementation should be 5.2-based rather than 5.1-based.
