I tried the reproduction recipe on my mac and couldn't reproduce, so
it may make sense to take this switch out? In any case, I've set my
automated mac build to include TTY tests

10.5.0 is pretty ancient at this point; I can well believe that the
upstream problem has been fixed. It would be nice if we knew in which
version it was fixed, though. Just dropping the restriction risks people
getting spurious failures if they are on an old enough version.

Do you want to roll a patch that checks $(uname) to see if we're on a
recent-enough version (where we can just be conservative, and assume
whatever version you have is the first one to fix it)?

No, there's nothing standard for comparing version numbers. Probably

    test "$(uname -r | cut -d. -f1") -ge 14

sufficient.
