So, in the end, I don't see any hope for you via this route, short of this:
register an object as changed in your __setattr__ without worrying at all
about _why_ __setattr__ was called.  Later, when you "do something" with
your list of modified objects, simply ignore any whose state at that time is
UPTODATE.  Those are exactly the objects whose state got materialized but
didn't change thereafter.

The long term solution to these are other related use cases is to start
using events in ZODB.  That is, ZODB should use zope.event to report
happenings of potential interest to applications.  Then applications
can use the event system to be notified and provide additional
functionality.
