procutil: make mercurial.utils.procutil.stderr unbuffered For most Mercurial code, it doesn?t make a difference, as the ui object flushes stderr explicitly (after the change, we could get rid of the explicit flush). One example where it makes a observable difference is mercurial.util.timed(). Without the patch, the time is not immediately shown on Python 3. With the patch, it?s shown immediately on all Python versions and platforms.
