I forgot... the extra KDE core stuff that gets launched with the app 
should die with it when you close it. If all goes well, that is ;-) But 
if you tend to use KDE apps frequently during your every day work, it's 
maybe not a bad idea to start the KDE services at login and keep them 
alive since then KDE apps will start up faster.
