After a relogin, this is also true here at this moment, dbus-daemon uses
about 4% of one of my two cores. After 26 days of uptime, its total CPU time
is 1380 minutes, Followed by udisks-daemon with 990 minutes, and then mysqld
with 25 minutes.

Right now I have three dbus-daemon processes (one owned by messagebus, two
owned by my user), with a total of 4.5M only. The excessive usage of 750M (I
noticed this for the first time) probably was a memory leak. Like with KWin,
where it always happens after some days of being logged in.

I run some more applications. 9 Konsole tabs, two Dolphins, a Konqueror as
file manager, Amarok, TV-Browser, Kontact, Chromium with 15 tabs, KMyMoney.
That's what comes up after login, after a while of being logged in more
stuff is running. Yesterday I had a Windows running in vmplayer, that may
use 512M.
Right now, 4.7G of memory is needed (free -m, -/+ buffers/cache entry).
[Later]
Whoops, forgot to actually send this mail. Ten hours later I have another
dbus-daemon process, owned by root, but memory their usage is the same.
5250M of RAM are needed now altogether.
