According to the docs, it's supposed to be called once at the start, and again 
at the end. But it's being called for every single change. In these calls, I 
call beginUpdates and endUpdates on my table view. Partway through, my table 
view complains about mismatched inserts/deletes, etc.

The action that initiates this is a bulk change to a bunch of the entities in 
the NSFetchedResultsController's set. The FRC has a predicate "removed == 
false". The bulk update changes "removed" to true. I get a deleted change type 
(not updated) for each object, bracketed by will/did change calls.

All of this happens in the -[MOC save:] call after the updates.

Am I missing something?
