editingcontext.objectsWithFetchSpecification( spec ) will always make
a trip to the db and execute SQL. Always. [Well, that _might_ not be
true when dealing with shared editing contexts or read-only entities,
actually. I don't use either of those things; it's possible they
change this].
The SQL executed which determine _which_ EOs are in the returned
list. Now, the actual _values_ of those EOs----the values returned by
the SQL may be ignored, if acceptable snapshots for the EOs already
exist. But the trip to the database happens anyway, and determines
_which_ objects are returend. Always, so far as I know (someone tell
us if shared ECs or read-only entities can change this assumption).

Kent,
Art will be able to confirm this, but it may be possible that the
fetch isn't going to the database if the objects have already been
fetched in a previous operation.
Just a thought.

Ray, I tried different methods and no joy. Art, I added the
EOAdaptorDebugEnabled and discovered that specific fetch is not
even going to the database. I would presume EOF would complain if
it was a malformed qualifier? I'm stumped.
