Konstantin Belousov 67388836f3 Store the bottom of the shadow chain in OBJ_ANON object->handle member. ... The handle value is stable for all shadow objects in the inheritance chain. This allows to avoid descending the shadow chain to get to the bottom of it in vm_map_entry_set_vnode_text(), and eliminate corresponding object relocking which appeared to be contending. Change vm_object_allocate_anon() and vm_object_shadow() to handle more of the cred/charge initialization for the new shadow object, in addition to set up the handle.
