But we need a different kind of "setnil". For reference counting, the
usual "setnil" must decrement the count of the previous value, but
the "setnil" of a new reference cannot do that.

Destruction of non-stack references ocurr mainly when Lua destroys an
object, so this is already controled by the garbage collector.
