/etc/xdg/autostart/pulseaudio.desktop
pulseaudio daemon run by GNOME autostart from this file is not actually 
used by the thin client session.  This pulseaudio runs 
/usr/libexec/pulse/gconf-helper, which can keep processes leftover after 
logout.  In my tests however they seem to die within a minute of logout, 
but your logs indicate they sometimes don't.

http://kojipkgs.fedoraproject.org/packages/pulseaudio/0.9.14/3.fc10/
I built a new pulseaudio for Fedora 10 that prevents pulseaudio daemon 
from running upon desktop login when it wouldn't be used due to 
PULSE_SERVER being set.  This should improve it a little bit.  Please 
upgrade this ON YOUR SERVER and let me know if it improves that part.

But it seems there are other bugs of other processes not dying after 
logout.  Please identify those and tell the list.
