void traverseForObjects	(	NSArray	sourceObjects,
		boolean	skipFaultedSourceObjects
	)

Traverse through all relationships represented by this keypath for sourceObjects using batchFetching to optimize roundtrips to database.

This method assumes the EOObjectStoreCoordinator has been externally locked.
