Well the good news is that my test box now oopses on about 2-out-of-3 boot
attempts. But that gets tiresome.

Optimistic, too.
I'm thinking that this can be fixed from the other direction: just before

going-away tty ineligible for concurrent lookups. Do that by setting
tty->driver->ttys[idx] to NULL. Maybe.
