At the very least, upstart does not hold a tty while running:

mbt at fennel:~$ ps -eaf|grep init
root         1     0  1 12:14 ?        00:00:02 /sbin/init

lsof also doesn't show any TTY lines open from the process.  However,
when it starts, if memory serves, /dev/console is the TTY line in use.
If that eventually becomes tty1, that _might_ explain the behavior that
you're seeing.
