No, it isn't, which is why I wrote "vote against", not "veto". But it's
an easily-fixed nuisance. ISTR Julian mentioned he had similar
intermittent problems on Linux ... which might nor might not have the
same cause.

Your fix in r1544303 is for prefork, which is the default on OSX 10.10.
If I can use neither event, nor prefork without the fix, there aren't
many options left. As for your point (3), I propose you use that
argument to all the people who're bound to complain about a broken
davautocheck. :)

Ho hum ... if that's the case, we may as well say that the whole test
suite is a convenience feature and not worry about test failures during
release testing.

I suspect a lot of downstream packagers tend to rely on 'make
davautocheck' to vet their packages, and HTTPd 2.4 is becoming more
widespread ... which is why I think it makes sense to fix this
"convenience" for our users, even if we know there are workarounds.

I'm not going to try to stop the release, more than I've already done.
But I won't sign the tarballs; IMO, the release is broken, and given
that we've had a fix on trunk for more than a year, there's no reason
not to fix it. It's not as if we're in any particular hurry to roll
these releases right this minute.
