Sorry for the delay, I wasn't around yesterday... :-)

Ok, so I exited from firefox, skype and emerald (replaced it with
default kde4-window-decorator). The swap usage dropped halfway, from 1 GB to 
0.5 GB. Some memory also got released. This is the new top output:

The system regained some responsiveness, but still appears mainly sluggish.

The problem isn't the actual load, but the fact that memory consumption 
increases without bound over time. I'll try to use Konqueror for a day instead 
of Firefox, and I'll try to refrain from keeping skype and emerald running. If 
the swap usage keeps increasing, the culprit is somewhere else... I'll wait 
and see.

Best, :-)
Marko
