Yeah, I think that's better than using fstab anyway, since this way we get
them all with limited processing. Wish I'd thought of it. :)

I suppose this is mostly a style difference, but I like to avoid all those
subshells if we can. I also think it might be a good idea to wait a second
between unmounts, just to be paranoid. How about:
mount | while read dev d1 mountpoint d2; do
case "$dev" in
/dev/fuse[0-9]*) umount $mountpoint ; sleep 1 ;;
esac
done
sleep 1
> kldunload $kmod
