Wow, that's extreme. I compiled PyKDE on a Centrino 1.4 GHz in less then
30 Minutes having only 512 Megs Ram (and 700 Swap), while actually
running KDE, including amarok (which is for a music player quite
cpu-hungry) and writing some mails (in a xfce4-terminal, which is also
quite cpu-intensive). As I said, the system slowed down really good but
there were still at least 30 Megs Ram unused and I don't think that any
swap got used for that. 

Oh that's the concatenated version of PyKDE I'm talking about, the
non-concat version is taking about double or tripple the time, but uses
much less memory.
