With this patch applied, my X server fails to exit when I do the normal
logout thing from the KDE menus.
The distro is FC5, SELinux is enabled. I start X via `startx'.
All the X clients have gone away, but the server continues to run. Black
screen with just a mouse pointer which still responds to movement.
This happens with CONFIG_SECURITY_FS_CAPABILITIES=n as well as =y.
