-// DBusThreadManager manages the D-Bus thread, the thread dedicated to
-// handling asynchronous D-Bus operations.
-//
-// This class also manages D-Bus connections and D-Bus clients, which
-// depend on the D-Bus thread to ensure the right order of shutdowns for
-// the D-Bus thread, the D-Bus connections, and the D-Bus clients.
-//
-// CALLBACKS IN D-BUS CLIENTS:
-//
-// D-Bus clients managed by DBusThreadManager are guaranteed to be deleted
-// after the D-Bus thread so the clients don't need to worry if new
-// incoming messages arrive from the D-Bus thread during shutdown of the
-// clients. The UI message loop is not running during the shutdown hence
-// the UI message loop won't post tasks to D-BUS clients during the
-// shutdown. However, to be extra cautious, clients should use
-// WeakPtrFactory when creating callbacks that run on UI thread. See
-// session_manager_client.cc for examples.
