I just came across this great Apple NSTreeController / NSOutlineView example.
It incorporates a lot of 10.5 style techniques into one example.

Just encapsulate your code in a @try / @catch() block to ensure that

Each persistent document has its own Core Data stack. When you close
one, and reopen it, it has a new NSPersistentStoreCoordinator,
NSManagedObjectModel, and NSManagedObjectContext.

Each NSOperation is, conceptually, its own thread. In addition to

There were a couple of problems.

After doing this, it all works.
