These seem to be slowing KDE, Plasma startup. (After latest dbus upgrade off Sid?), a dbus instance owned by messagb... and a hald instance owned by haldaemon.... are taking even idle CPU resources. Pulseaudio seems to require these for user-startup should the user want to start pulse daemon. Otherwize, these simply sit and so does KDE. Is this a new bug? Need to renice them? Fix?
