In accordance with the standards for munlock(2), and in contrast to vm_map_user_pageable(), this implementation does not allow holes in the specified region. This implementation uses the "in transition" flag described below. o Introduce a new flag, "in transition," to the vm_map_entry. Eventually, vm_map_delete() and vm_map_simplify_entry() will respect this flag by deallocating in-transition vm_map_entrys, allowing the vm_map lock to be safely released in vm_map_unwire() and (the forthcoming) vm_map_wire(). o Modify vm_map_simplify_entry() to respect the in-transition flag.
