can iostat _really_ behave like top ?

[Ensel Sharon]

When I run `top`, I get a single screen (ncurses ?) that refreshes itself
_in place_.

However, when I run iostat in "top mode":

iostat -h -w 1

it does not refresh in place, rather it creates line after line,
eventually scrolling off the screen, etc.

Is there any way to use iostat like top, so I can have a single,
constantly refreshing screen to look at once in a while ?

Thanks.
