Comment 7 for bug 441828

I can basically confirm this, but the behaviour on my system is slightly different:
* The hyperactivity of the cpu is shared between gnome-system-monitor (~50%) and dbus-daemon (~40%).
* The hyperactivity starts as many times as I start gnome-system-monitor when a CD is mounted, and it goes away when I eject the CD.
* However, the hyperactivity does not restart when I reinsert the disc while gnome-system-monitor is running.
* Sometimes gnome-system-manager refuses to close (and I xkill it), sometimes it goes away voluntarily. I don't see the logic.

"dbus-monitor --session" gives enormous amounts of output (some kind of data structure definitions or so). If you want, I can record some of it, just tell me to.
