I think all the user-space allocated pages point to the same zeroed/shared

> user-space allocated pages
We were talking about kernel-space allocated memory... Having a stock of cleared pages for user-space would probably also be an improvement (when user-space writes its first byte on a page), as long as clearing those pages does not wipe the memory cache (i.e. DMA to memory instead of processor writing).
