Just curious.

    #lang racket
    (for ([x 1000]) (displayln x))

The program above runs very quickly in DrRacket. I can hardly see other
numbers than the final ones.

For this program:

    #lang racket
    (for ([x 10000]) (displayln x))

the first, say, 1000, lines are done in an instant, but then at some point
it looks as if the numbers "count up".

Is it it enough to refresh the screen less often (when the buffer is
non-empty that is)?
