So you don't consider RAM a resource? :)
I just went and rebooted my workstation, here's a top from
just after the reboot, with the box idling on the xdm login prompt.

Also note that at that stage the X process has had the most
CPU cycles as well (which might be different if I could let it idle
for much longer - but I need to answer this e-Mail :D and gmail
doesn't work with lynx).
