My shutdown script does a 'swapoff -a'.
Further, the same script unmounts all file-systems "/etc/rc.d/rc.0"....
I don't think that the problem you are having is caused by this. Instead,
You probably have a task with an open FD that refuses to die during
shutdown. You can emulate exactly what should occur upon shutdown from
the keyboard (console, not over the network).
# kill -TERM -1
# sync
# kill -KILL -1
# cd /
# swapoff -a
# umount -a

Although the system is still "alive", you can hit the reboot switch or
turn the power off with no effect upon the file-systems that have been
safely put to bed.

On your next boot, they will be mounted immediately after fsck sees that
they were properly dismounted.
