Slackware :: Telinit 4 - Kdm - Open Console Session Prevents Shutdown - 64 13.37

I have a question regarding runlevels, shutdown procedure and KDM. I am on a freshly installed Slackware64 13.37 multilib system. The default runlevel in /etc/inittab is set to 3: multiuser w/o X.

Now, I log in as root and issue the command:

Code:

As expected, KDM starts up, and I log in to KDE (or another WM/DE) as a normal users. When I am finished, I either issues

Code:

In Konsole or click on Shutdown in the KDE menu. The shutdown process is initiated, as expected, but then it stops, and a window alerts me, that there is a session open by user 'root'. If I click OK, the machine is finally shut down.

Now, if I interpret this correctly, the behaviour of Slackware64 13.37 has changed here, compared to 13.1. In previous versions, the root seesion was closed, when I changed the runlevel to 4 with the telinit command. Now, the session remains open, obviously.

My question is: Is this the correct behaviour, and isn't this a security whole? An unnoticed (!) open root session while I am surfing the web as an unprivileged user in KDE could be dangerous, I think...

Is it misconfiguration in my system, or is this the way it should be?
