I believe the stale entries for console logins happen because there is
no inittab entry for tty7, so init does not update the entry at logout,
as it normally would do for a getty-style login.
I can add an explicit test to ignore the dm pid in reactivate. We may
also want to consider whether we need code which extracts the pid from
a utmp entry.
