-VM_FLAGS_SUPERPAGE_SIZE_*      to use superpages for the allocation. 
-See <mach/vm_statistics.h> for supported architectures and sizes (or use
-VM_FLAGS_SUPERPAGE_SIZE_ANY to have the kernel choose a size).
-The specified size must be divisible by the superpage size (except for
-VM_FLAGS_SUPERPAGE_SIZE_ANY), and if you use MAP_FIXED, the specified address
-must be properly aligned. If the system cannot satisfy the request with superpages,
-the call will fail. Note that currently, superpages are always wired and not
-inherited by children of the process.
