I think it's intended to guarantee that pam_close_session() is closed
when its parent "systemd --user" exits.  However, on my system it seems
that on user logout the main systemd (pid 1) usually SIGKILLs it before
it has the chance.  I think that's a bug, because systemd is supposed to
wait TimeoutStopSec between sending SIGTERM and SIGKILL.
