An alternative would be a persistent subobject of the synchronized
object (such that its modification does not modify the
"bobobase_modification_time" of the primary object).


I just notice that synchronization of structured (e.g. "ObjectManager")
objects might be a problem. As subobjects might also be synchronizable,
they, too, should get the correct times.
