 // Because GenericChangeProcessors are created and used only from the model

 // DataTypeController, which live before / after communication with model
 // threads begins and ends.
 // The GCP is created "on the fly" at just the right time, on just the right
 // thread. Given that, we use a factory to instantiate GenericChangeProcessors
 // so that tests can choose to use a fake processor (i.e instead of injection).
 // |sync_factory| is used to create AttachmentServicefor GenericChangeProcessor.
 // It is not retained after CreateGenericChangeProcessor exits.
