sbrk and brk are not POSIX.  However, any system that is a derivative
of *nix has sbrk and brk because there are too many softwares (such
as the Bourne shell) which rely on the traditional memory map
(.text, .data+.bss, stack) and the existence of sbrk/brk.
A key property of sbrk/brk is that new whole pages that
are supplied by the operating system *do* get initialized to zero.
Memcheck must support and honor this property.
