Requalifying as new feature.
In fact there is an API inherited from ORM to do that

	public ScrollableResults scroll(ScrollMode scrollMode) {
		//TODO think about this scrollmode
		return scroll();
	}

If the scroll mode is forward only, we can do a much better job than your current PR Markus heberling (thank you for it BTW .
We would not even need to create this huge array containing all results (sometimes nullifled as per your patch). We could simply decide of a fix forward only window (the fetch size probably), and use an array of that size.

Do you think you could explore this Markus heberling ?
