// advertises it through ExportedObjectManager on D-Bus. Command handling
// processes can watch the new D-Bus object appear and communicate with it to
// update the command handling progress. Once command is handled,
// DBusCommandProxy::Done() is called and the command is removed from the
// command queue and D-Bus ExportedObjectManager.
