Remove the file and see whether any disk space clears up.

Seriously, there's no good way to get the soft link count. You could try
``ofiles'' on machines where it works, but it isn't reliable.

If there were an enforce() call to enforce the new permissions on a
file, I don't know why you'd care who had the file open. After all, if
the permissions are still open, anyone could sneak in and out of the
file at any time, so your test wouldn't be reliable. And if they aren't,
why are you checking access if you don't want to cut it off?
