>Description:
	rc:  if rc_fast_and_loose is set to NO, it is the same effect as
		if it were set to YES.
	rc.shutdown:  if rc_fast_and_loose is set, rc.shutdown will abort
		prematurely if any of the shutdown scripts exit non-zero.
		This can leave processes hung in vnlock, preventing init
		from recovering and granting a single-user shell.
>How-To-Repeat:
	in /etc/rc.conf: rc_fast_and_loose=NO
	exit from single-user shell
	shutdown now
	wait (interminably); exit to ddb and ps.  Note processes hung on
		vnlock.  These processes will keep a single-user shell from
		getting there.	 This is arguably the wrong way to fix this,
		putting "# KEYWORD: shutdown" in the rc script, but it is
		certainly the most painless at the moment.
		By the way, you will now have to sync, discover that your
		machine will not sync, reboot and wait for fsck to finish.
