 Why not? I'm not convinced. The problem is that timeout is effectively
 backgrounding itself and leaving nothing in the foreground. If it
 wants to make its own process group, it has to take charge of the tty
 to match. There's no reason it can't do that. If you stick another
 shell in there instead of timeout it all works fine.
