When I need to know whether or not a managed object is deleted, often I fall 
into the trap of trying -[NSManagedObject isDeleted], forgetting that its 
documentation states …

  "… It may return NO at other times, particularly after the object has been 
deleted. …"

In other words, they should have named that method -isDeletedForSure, to 
indicate that the NO result is not reliable.

Anyhow, today I fixed a problem by using this instead …

   BOOL isDeleted ;
   isDeleted = [object isDeleted] || ([object managedObjectContext] == nil) ;

I'm not sure if it will work in all situations.  I suppose that sending the 
magical -processPendingChanges would be another workaround.
