The real problem is I don't think anyone is really paying attention to cleancache. Dan, something that might be useful to drive interest would be a demonstration of this improves performance on, say, a netbook using cleancache and zram, and how it is better than just using zram directly as a swap device. With maybe some numbers? That might get some interest from the community desktop distributions... - Ted
