i'm all for it ...
umounting the block device unmounts all of them but umounting a dir only
unmounts the last thing mounted there ...
mount /dev/hda4 /one
mount /dev/hda4 /two
umount /dev/hda4 -> /one and /two get unmounted
mount /dev/hda4 /boo
mount /dev/hda3 /boo
umount /boo -> only /dev/hda3 is unmounted
