I'm really tired of having my system with a load average ~ 5 and SWAP usage
when I have NO applications open (except KDE4, Kontact and some Konqueror, no
more).
This is the typicall output of "top" command when the system begins consumig
resources (with no reason):
top - 22:03:04 up 2:49, 1 user, load average: 4.79, 5.01, 4.22

I've no idea of why console-kit-dae, hald and dbus are consumig so much
resources so often!
It's really extrange for me the fact that "dstat" detects a high disk writting
operations:

Also, a "free -m" tellsme that SWAP is being used!:
total used free shared buffers cached

Perhaps this bug is not related to KDE, of course.
