Mike,
Each persistent document has its own Core Data stack. When you close
one, and reopen it, it has a new NSPersistentStoreCoordinator,
NSManagedObjectModel, and NSManagedObjectContext.
So any bindings to managed objects or their entity descriptions from
the old, deallocated persistent document are effectively invalid.
