I guess system monitoring should stop itself when screen is
blanked... no need to compute list of processes if user can't see the
output.

But I see that may be slightly hard for command-line tool like
top. .... but it still seems like right solution. Why waste power/cycles
displaying xclock at tty9 when user is looking at tty10?

waste power with that at all :-).
