I can't cite chapter and verse but I seem to remember this zeroing problem was solved decades ago by just introducing a bit which said this chunk of memory or disk is new (to this process) and not zeroed but if there's any attempt to actually access it then read it back as if it were filled with zeros, or alternatively zero it.
