Ok. In your constructor, you should lock a reference to
the Lua table (lua_Object), using the lua_ref function.
In the destructor, you should unlock that reference using the
lua_unref function.
If there isn't any other reference to the table, it should be
collected in the next garbage collection cycle.
(see http://www.tecgraf.puc-rio.br/lua/manual/manual.html#5.8)

Then, if you really want to force a gargabe collection cycle,
you can use the lua_collectgarbage function.
(see http://www.tecgraf.puc-rio.br/lua/manual/manual.html#5.3)
