BTW about other operating systems:
It looks like FreeBSD is already clever enough to use super pages as
it calls them[1][2]. This is something like Linux's 'transparent huge
pages' except apparently somewhat more transparent. Though I wonder
if there is some advantage in adding a MAP_ALIGNED_SUPER flag to the
mmap request.
It looks like MacOSX can do it with VM_FLAGS_SUPERPAGE_SIZE_ANY but
such mappings are not inherited by child processes.
