 // If you need multiple batches of work to be done in the process, use
 // StartBatchMode(), then multiple calls to StartFooBar(p), then finish with
 // EndBatchMode().

 // avoid a use after free since this object is deleted synchronously but the
 // client notification is asynchronous.  See http://crbug.com/108871.
