Are there any other threads doing anything?
This smells like a deadlock to me.
Can you open the same file using the plain CoreData (non document
based) app?

I've got a really simple application of core data. It's a document

have an opaque bundle/directory data format and the core data is
only a tiny part of it.
Its hanging on the call to:
persistentStore = [persistentStoreCoordinator
addPersistentStoreWithType:NSXMLStoreType configuration:nil URL:url
options:nil error:&error];
with 100% CPU usage.
I did a sample in the activity monitor:

Why on earth there would be mentions of HTTP and Cookies for a
file:// URL has me puzzled. I'm also puzzled how my tiny bit of
code, which is basically like the core data sample app, it just
saves the managedObjectContext in saveToURL:.
