     * perform some cleanup. E.g., if the SyncAdapter received a bad entry from the server
     * when processing a feed of entries, it may choose to drop the entry and thus make

     * error occurred. This is considered a hard error.

     * local storage and starting over frmo scratch. This is considered a hard error.
