   // Initialize the sync manager.  |database_location| specifies the path of
   // the directory in which to locate a sqlite repository storing the syncer
   // backend state. Initialization will open the database, or create it if it
   // does not already exist. Returns false on failure.
   // |event_handler| is the JsEventHandler used to propagate events to
   // chrome://sync-internals.  |event_handler| may be uninitialized.
   // |sync_server_and_path| and |sync_server_port| represent the Chrome sync
   // server to use, and |use_ssl| specifies whether to communicate securely;
   // the default is false.
-  // |blocking_task_runner| is a TaskRunner to be used for tasks that
-  // may block on disk I/O.
   // |post_factory| will be owned internally and used to create
   // instances of an HttpPostProvider.
   // |model_safe_worker| ownership is given to the SyncManager.
   // |user_agent| is a 7-bit ASCII string suitable for use as the User-Agent
   // HTTP header. Used internally when collecting stats to classify clients.
   // |invalidator| is owned and used to listen for invalidations.
   // |restored_key_for_bootstrapping| is the key used to boostrap the
   // cryptographer
   // |keystore_encryption_enabled| determines whether we enable the keystore
   // encryption functionality in the cryptographer/nigori.
   // |report_unrecoverable_error_function| may be NULL.
