[ale] "busybox" looping?

[Robert L. Harris]

  Problem is that if the remote console (tty consoles in offices in and
out of the country) is slow and you hit enter to get the console to
respond, it doesn't because of lag, you hit enter again thinking it
wasn't connected, you just started dhclient and hosed the box.
