The analysis by Alan Watt of the link bug is correct.

The code shown by mi-cec!dvk does have the bug.

V7 does not have it, though it does have a fairly innocuous race.

4BSD does not have it, and it fixes the race correctly.

I doubt if System III has it, since I just looked at a successor
and it is like V7.

So the bug has, I hope, narrow distribution.  It is a serious one.
