But this is *not* malloc(). It's mmap(). Are you prepared to guarantee that there are no applications out there that don't rely on anon mmap() giving zeroed memory? The MMU-mode clearing is done for security reasons - there shouldn't be any leakage between processes, and because the zero page can just be faulted in. Personally, I'd prefer to maintain compatibility with MMU-mode wherever possible, but I'm happy with overrides like the MAP_UNINITIALISED flag suggested.
