Thanks to everyone that responded. One off-list message I received made me think about the problem a little more, and after some debugging, I realized I had a PEBKAC problem on my hands. My app does some fetch requests to check on existing data in the database, compares it to what's in a non-CD model, and deletes objects if certain bits of data are missing. In this case, there are several data structures sharing a common entity. I just didn't count on - executeFetchRequest: searching both the persistent store and the objects that were inserted but not saved. D'oh! Making the predicate more discriminatory worked around this, and now all is well.
