-// 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.
