1) Allow unique metatables for lightuserdata, that also respect __gc.
lightuserdata is a value type. `__gc` doesn't work well with value types ...
lua_pushlightuserdata( L, 0x1234 );
luaL_getmetatable( L, "metatablewithgc" );
lua_setmetatable( L, -2 );
lua_pushvalue( L, -1 ); /* duplicate lightuserdata */
lua_pop( L, 2 );
/* should the __gc method really run twice now? */
-spc (I can't let Soni have all the fun here ... [5])
