I'd been wanting to do this for ages, but Jake implemented it on the sparc64 a while ago now and he kinda shamed me into doing it. :-) The main difference is that sparc64 doesn't have to go to the trouble of intercepting the pmap_release() since the VM hardware is different and it doesn't have to worry about a potentially borrowed page directory getting bzero()'ed.
