Processes always get zeroed pages from the kernel. This is the case
for all Unices, and has been for decades.
Well, providing zeroed pages to processes is not quite similar to
explicit cleaning of pages after use as some security standards
demand. That's why I'm asking. The "Z" malloc option seems to be
suitable but it's actually for debugging.
