Oh yeah; I forgot about screen and tmux.
I just tried it in screen, and `os.system('clear')` does not clear the
scrollback used by screen.
I think that if we go ahead with this, we shouldn't allow lack
of support for screen and/or tmux to stand in the way. A 99%
solution is better than a 0% solution :-)
