    Description

      Leaving a QML application (using qmlviewer) running on the N900 makes the
      battery go flat very quickly. Especially troublesome, this happens even if the
      application is not the current visible one.

      With no user input and no UI animations, the UI must not be continuously
      redrawn. Further, when the application is in the background, all UI animations
      and redraws must be suspended to preserve battery. Event loops must not
      be spinning unnecessarily. Qt/QML must not prevent the device from going to
      sleep.
