I'm not sure the above is exactly true.  It's perfectly safe for
the C finaliser to call back into Lua, and I've got a feeling that
the finalised objects can indeed be resurrected - at least
there's no documented warning, IIRC, about making a new long-living
ref to the object in question, within the finaliser.
