Re: zero filling pages

A single process on your machine is exploited, and is now running malicious code. Without zero-filled pages, this process could just repeatedly call vm_allocate and examine the unallocated pages on your system. It could then, search for recognizable patterns in the pages (credit card numbers, addresses, social security numbers, etc.).

I wonder if perhaps vm_allocate could be modified so that it tries to return memory last used by the same process, and thus not needing to be zero-filled?
