No, the dtor isn't in any particular spot.  It just comes in the
`natural' virtual function place.

Nope.  It is a waste of space.  You cannot meaningfully for anything
with the table without knowing how many elements are in the table.
You will have to find that information out some other way.  One
thought, is to put more member info into the rtti data, and then you
could use it.
