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.


Your motives for doing whatever good deed you may have in mind will be
misinterpreted by somebody.
