Well, I could add a routine to the TTY layer that does that. The reason
why the TTY layer is a little `lazy' with deallocating TTY unit numbers,
is because I want to be absolutely sure processes agree they do not use
the TTY (device name) anymore.

I'll see if I can add a sleepable tty_gone() routine one of these days.
