Not sure, but I believe that -f behaves much like -l, and as long as something 
is in use, like a process with a file open or cd into the mount. As long as the 
process doesn't try to use the mount, other than what's n cache, it goes on 
happily, and only when no process knows, or thinks it knows, about the umounted 
f/s it won't truly go away.

In either case, the name of the big hammer is lsof, assuming you really want to 
umount and are willing to accept collateral damage.
