A larger boost to keep-the-page-in-memory priority for pages referenced by "interactive" processes might be in order. Either faster vmscanning simply a higher priority for pages found to be used. Might not be too hard to implement either.
A larger priority for page-in I/O due to interactive process too might help too. Some modification of Andrea's elevator. But that doesn't seem so easy.
