I think there is a misunderstanding here; I believe that OP is referring to "infinite scrolling" where the list items are fetched from the server n items at a time as you scroll and wishing for a toolkit that keeps the data in memory and recycles elements as you scroll (which is what everyone is recommending). When OP says "hack" they are talking about loading data as you go, not windowing, which is what you are talking about.
