It doesn't work for me :-(

[root tc1000 mnt]# mount /dev/sdb1 /mnt/tmp
[root tc1000 mnt]# cd /mnt/tmp
[root tc1000 tmp]# umount /mnt/tmp
umount: /mnt/tmp: device is busy
[root tc1000 tmp]# umount -f /mnt/tmp
umount2: Device or resource busy
umount: /mnt/tmp: device is busy

This has to work for usb-auto-umount or it'll leave
the usb-drive's icon on the desktop if any file's
still in-use when it is unplug. Any process that
using the files will crash but it's safer than
allowing even more confusing access to invalid
filesystem.
