I have realized that the modification done by rvs speeds up another process. When I zoom in a page, it takes time, as normally. But when I have finished reading the zoomed piece, and I zoom out to full page, now the reader performs it quickly, without the "wait, please" popup. Before applying this patch, the zooming out action took longer, and the popup appeared. So it has been improved by the "corrected pre-fetching".
