[Guido Günther <guidog src gnome org>]

commit b41a0532379e5be2a96577c6c66ae20d956403d3
Author: Guido Günther <agx sigxcpu org>

    Add no-persistence test option
    
    This allows us to test notification systems without persistence.
    We can then e.g. embed it into an Xnest sessions's xfce4-panel.
