	Oh; hmm, well - it will mean that if you are doing a fairly fast
operation, you are likely to see only two frames per second of the
scroll-bar, so perhaps you see only 15%, and 75% and then it disappears.
Perhaps more interestingly, if it is a sub 500ms operation, perhaps you
never see the scroll-bar at all (and no associated UI flash-bang around
accommodating it) - though perhaps we do that now.

	From a user-experience view, things that previously were slow - spend
their time rendering pixel-by-pixel increments in the scroll-bar at high
frequency now get substantially faster. Of course if something is
-really- slow, then we'll still get that pixel-by-pixel look - just
updated only at 2 fps.

	Oh ? I get my mails back from the list, and it should be un-moderated I
think; Thorsten ?
