>Description:
When an ext2fs file system is mounted, FreeBSD 5 does not shut down properly,
the syncer gives up on a few buffers, and at next reboot, some FreeBSD file
systems are still marked dirty and need to be fsck'd.

This has been mentioned and acknowledged several times on current@,
but no-one cared to fix the problem. Hence the PR.
	
>How-To-Repeat:
mount_ext2fs SPECIAL /mnt  # replace SPECIAL by a /dev/something that points
			   # to a valid ext2 or ext3 file system
reboot
