mmalc,

I would expect to see a  
NSManagedObjectContextObjectsDidChangeNotification notification on  
load by virtue of the fact that managed objects are being inserted  
into the managed object context.  There are three keys that can be  
part of the passed userInfo dictionary: inserted, updated and  
deleted.  When loading the data from the store, are they not being  
inserted into the managed object context?   By extension, shouldn't  
this trigger the NSManagedObjectContextObjectsDidChangeNotification  
notification, alerting any registered observers?
