clean close-down of KDE apps

[purslow at sympatico.ca]

i use several KDE apps regularly, which start several KDE processes.
when XFCE exits, these processes appear on screen having been killed.
at the end of 'startkde', there are lines for clean-up of KDE, esp :

  kdeinit_shutdown
  dcopserver_shutdown
  artsshell -q terminate

but of course these don't get run when XFCE closes down.

somewhere in the past few months there was a note -- mb in XFCE-user --
recommending to add these or similar lines to an XFCE script,
but i can't find it among my usually well-ordered archive of useful msgs.

does anyone have suggestions which lines are needed & where to put them ?
