It would be nice if reboot could be made to force a reboot. Perhaps using a
flag. I have a NetBSD 5.0 Web server where any process accessing the Web
content partition would get stuck in state D (disk wait) waiting on "tstile".
(I suspect this is a wapbl issue since I have not seen the problem since
remounting the file system without -o log.) Reboot hung after printing
"syncing disks", requiring physical access to restore the server.
