CoreData - How to monitor progress during long fetch ?

Hi,

PROBLEM : I am writing a CoreData app. When the app launches, about 1500 instances of the same entity are created (ie loaded from an XML persistence store) in order to populate an NSTableView (using bindings). It takes a lot of time (about 5 seconds) to load data into the table view. During the process, UI is frozen. So bad user experience ! How can I monitor the fetch process in order to display some kind of a progress indicator ?

Thanks for your help.
