I'm not. But if Exmap doesn't include this, I'd have to redo everything and
I'm not sure how to measure it anyway. Doesn't seem to be worth the work just
to possibly find out that the absolute numbers grow but the relative
distances between WMaker, Xfce, KDE/GNOME stay about the same. Especially
given that it took me so long to finally write all this down.

When starting what setup of KDE? 40-60MB? 5% overhead seems quite a lot.
