In the documentation for NSPersistentDocument's method -managedObjectModel it
says the following addition in a subclass can be used to improve efficiency if
all the documents share the same model.
> - (id)managedObjectModel {
> static id sharedModel = nil;
> if (sharedModel == nil) {
> sharedModel = [[super managedObjectModel] retain];
> }
> return sharedModel;
> }
If the app is running on 10.6 and returns YES for
canConcurrentlyReadDocumentsOfType I'm assuming some sort of synchronization
would be necessary here?
