    Please do not add or the requisite patch to stable tree.

    Although this is a real potential issue, it was only found during code
    inspection. It has existed for more than 10 years and I am unaware of
    anyone hitting this in actual use. In addition, this proposed fix will
    likely be updated/simplified based on more discussions.
