luarc, a reference counted version of Lua 5.02, is pretty efficient.  The
mark/sweep collector still has to run for cyclic tables, but for everything
else, it's better than any other solution I've played with.  As an example,
the mark/sweep pass in Amped 1 took over 60 milliseconds.  Given the number
of tables/strings/collectable data generated per frame, luarc would take a
fraction of a millisecond.

luarc is available at http://luaplus.org/.
