You are implying that KDE does not excessively eats memory.
I think you will change your opinion if you boot your box with mem=128M
kernel parameter and work with that setting for several days.
Use this script (w_process):
watch -d -n3 'pmap "'"$1"'" | grep "^[0-9a-f][0-9a-f]* " | sort -r -t " " -k2,999 | head -20'
and pick any KDE process to watch. For example, my KMail:
# w_process 1884
0825c000 12684K rwxp [heap]
40cfb000 6180K r-xp /.share/usr/app/qt-x11-free-3.2.3/lib/libqt-mt.so.3.2.3
4062f000 2612K r-xp /.share/usr/app/kde-3.1.4/lib/libkio.so.4.1.0
40013000 2584K r-xp /.share/usr/app/kde-3.1.4/lib/libkhtml.so.4.1.0
408d5000 2092K r-xp /.share/usr/app/kde-3.1.4/lib/libkdeui.so.4.1.0
08048000 2040K r-xp /.share/usr/app/kde-3.1.4/bin/kmail
40b1c000 1412K r-xp /.share/usr/app/kde-3.1.4/lib/libkdecore.so.4.1.0
416b7000 1080K r-xp /app/glibc-2.3.2/lib/libc-2.3.2.so
41498000 752K r-xp /.share/usr/X11R6-4.4.0/lib/libX11.so.6.2
4049c000 744K r-xp /.share/usr/app/kde-3.1.4/lib/libkdenetwork.so.2.0.0
[heap] is basically how much memory was malloc()ed.
It's KDE 3.1.4. I am interested how much KDE 3.4 eats.
