NSPersistentDocument Revert Question

Hello list,

I'm having trouble tracking down what I would think to be a simple 
answer for a simple question:

In my NSPersistentDocument based application (10.4), selecting 
'revert' from the file menu creates new window controllers (I assume 
it is just re-opening the original document), but it doesn't 
deallocate the old window controllers from the document that was 
edited pre-revert.  This creates a ton of "'entityForName' could not 
locate an NSManagedObjectModel" error's due to the fact that the 
document these window controllers were retained in no longer exists. 
Am I doing something strange or do I need to manually deallocate my 
window controllers in my NSPersitentDocuments' revert override?

Thanks,
Mike
