Well, it's true that we can't point to specific field reports and say
that this will fix those. But it's not like our Windows port is so
rock-solid-reliable that we should give it the benefit of the doubt
about existing behaviors being correct. We do know that the code path
in question is used in previous branches --- we put it there for a
reason --- and I think it's probably possible that it gets exercised
in corner cases, even pre-9.5.
