Unix/Linux is a multiuser system. If a user had the ability to lock the
system against anyone else, I would call that a bug.

As it is, a user has the ability to lock its sessions. That's the purpose
of xlock and likes.

And if the same user or another user has the ability to switch to a new
console and start its own X server or shell, I call that a multiuser

So, as I see it, one is doing things as it should...
