Haven't nailed it, but there's something going on with X and tty... Among other things, when I telinit 3 && telinit 5 the tty keeps switching between 7 and 8 (nothing else running on either tty). It would appear that somehow the tty deallocation isn't complete when X restarts. Also, X grabbing a tty seems to be a requisite step in recreating the sky2 issue.
