Right and most drivers just check SHARED. But if we are being documentative why they check shared is because the driver cannot tolerate COW. I think if someone is cargo culting a diver and sees 'vma_never_cowable' they will have a better understanding of the driver side issues. Driver's don't actually care about private vs shared, except this indirectly implies something about cow. Jason
