This is the normal way to keep references to objects.  I asked Jim Fulton at
IPC8, and he basically said "don't use _p_oid", which means this is the only
way.  Of course, once the observer interface is more well developed you
won't need the Catalog part.

Yup - no object_reindex() every time you change the object, no need to
inherit from anything.  You can  have automatic catalogging in any DataSkin
object trivially, with no change to your class.
