You're right Chesney. I assume that the faulty DC wasn't noticed because it
was probably never really used ;-)
Your solution should make the DC to work properly. We could even get rid of
the second counter by simply decrementing the counter upon deletion. If the
counter is 0, then the file can be deleted. Nice illustrations btw.
