In directory netbsd1:/var/slash-tmp/cvs-serv9445

Modified Files:
        vm_object.c 
Log Message:
Unlocking the target object within vm_object_overlay() is safe, since
the backing object is protected the OBJ_FADING flag.

In vm_object_deallocate(), gain a reference to the object we try to
collapse (per Manuel Bouyer).
