Can we add a comment about why we're un-buffering stderr here?  Also I
think we might as well just do it unconditionally (not just on
Windows) because POSIX doesn't define the circumstances in which
stderr is fully buffered (it predicates it on what is an "interactive
device" but doesn't define that term).
