Ideal if it was working, but I seem to remember trying it and it made
no difference. Me thinks I tried it on a non-nfsfs though, and -f might
only work with nfsfs?

The other options I can see are fiddling the timeouts in the mount
options, or using fuser to kill things off before umount. As I said
earlier, the mount options hard/soft/intr are useless in this case
(no way to pass any signal to the blocking process).
