    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
    release_dev() calls close (dropping BKL), if tty->count==1, make the
    going-away tty ineligible for concurrent lookups. Do that by setting
    tty->driver->ttys[idx] to NULL. Maybe.
