It could, but it hasn't in the last many years that we've lived with it
without anyone noticing, so we can live with it a few more I think.
And the effect of the bug seems rather minor.
IOW the urgency is very low.

I don't find it simple at all. E.g. it doesn't seem obviously safe
(e.g. what if the X call ends up making a longjmp and hence skipping the
unblocking of sigio? Seems highly unlikely, but we do make longjmps in
not-completely-different circumstances (e.g. to avoid killing Emacs when
an X connection dies), so I think that proving such a longjmp can't
happen would require a serious code analysis, i.e. pretty far from
"obviously safe").
Low urgency, non-zero risk, I'm surprised you'd even bother to lobby for
inclusion one day before the actual release.
