Core Data: How to Observe "dirty" State?

Does anyone know how to "watch" for the dirty state of an
NSManagedObjectContext (if that's where it is applicable)? I imagine the
same way that NSPersistentDocument can do it, if that is feasible.

I know I can observe all of the properties in a managed object and set a
flag when a change occurs (and also check NSUndoManager so I know when I get
to a properly "clean" state), but I was hoping there was a cleaner and more
robust way.

TIA,
