In theory, this is fine. But on my system (512 MB RAM) it's not always like 
that. After a few hours of work with a lot of opening apps and documents and 
images, it dips into swap, and it does that even when I close most apps. So 
before I can continue working I have to reboot. This shouldn't be necessary. 
Is it because I have a 'pre' kernel? I wondered why they made the 2.2.18pre21 
the default kernel for potato when they otherwise put software in it that are 
sometimes not usable because they're so ancient.
