Editing contexts broadcast (via NSNotificationCenter) notifications when changes are made (see EditingContextDidSaveChangesNotification) and other editing contexts listen for these. If you dispose of an ec as soon as you no longer need it, NSNotificationCenter and the other ECs have less work to do.
