Description of Problem:

If you have nautilus running, ie the default gnome configuration and pull
up a terminal and mount an nfs share and decide to umount it you will not
be able to if you have actually cd'ed into it. This happens even after you
have left the directory, evidentally nautilus is detected that your in
there and is using it.


How Reproducible:


Steps to Reproduce:
1. login into gnome with nautilus running
2. mount an nfs share
3. try to umount it after browsing in it.

Actual Results:

umount wont work because it is busy

Expected Results:

it should allow umounting
