Robert, Sure this could be a good PR to verify but as the condition does not exist on 8.2-STABLE as of today, I feel that you are just going to be chasing a ghost in the machine.
This does not say that it wasn't relevant back then but as of now it is. The PR didn't specify any realness to what was seen as I can tell from reading it over it just says it disappeared and there could be many possible reasons for that happening that fall back to the user in the chair. Attached is output from the script with a little more verbosity to show its current status. If the same can still be reproduced on a recent -CURRENT system then so-be-it but otherwise this can be closed.
