You've already found the other one, so no need to tell you where that
is. A third from Brandon Ros was only ever on Slack, but that didn't
add new information IMV. I haven't talked to Brandon myself (just the
other 2).
BTW, it's possible that Brandon wasn't using foreign keys or shared
locks at all -- I didn't verify that part. I can only say for sure
that that was the case with the other 2 reports.
