The session is still marked as "closing" but because processes still
exist it never quite dies. And yes, the kill processes option (which is
a nice thing to enable if possible) would indeed kill the screen.

It would be really nice if screen somehow escaped, but if the pam* calls
need root then I think some other way would be better (perhaps with
logind doing some of the setup work... dunno).
