Very, very weird. You all seem to have some weird issues with
dbus-daemon that I don't have.

(times retrieved with ps axS, memory consumption retrieved with htop)

On my 77-day uptime server runing Debian 5, dbus's total time is 0:00.
(That's with ps axS) virtual memory of 21M, resident of 900K.

On my gentoo desktop, 8 days' uptime, I show two dbus-daemon
processes, both with 0:00. Both with virtual of 19M. One with resident
of 984K, one with resident of 808K.

On my router, Debian 6, with 4 days' uptime, ps axS shows 0:00 for
consumed time. 23M virtual, 968K resident.
