>Description:
It's pretty easy to hang `umount -f' and get inaccessible
directories.
>How-To-Repeat:
NFS mount a file system over an interface that is detachable.
Detach the interface.
Try `umount -f' on the file system. It hangs.
But what is much worse is that the directory which had the
mount point is no longer accessible. E.g., I did `umount -f /mp3'
and now I can no longer access `/'.
>Fix:
Unknown.

Amendment: It is in fact just the mount point that is inaccessible after
umount hangs, not the directory where it resides. Mea culpa.
