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?

Well, my web browser already has an option 'animate once'. No need to
waste power with that at all :-).
