That comment pertains to the lines *after* it, dealing with
ENOPROTOOPT, not the line before it. Both the comment and the
ENOPROTOOPT code following it appeared in 9.10.0; neither was there in
9.9.0. So there's no basis for claiming that ENOBUFS "was seen".

That's not a fix, that's just making the problem harder to trigger and
therefore less likely to be fixed.
