Is that the one you suggested trying to fix by calling write() instead
of fprintf()? If so, I can't think of any good reason not to do that
anyway. (I assume we're not worried about the use of vfprintf(stderr,
...) in write_stderr().)
That really means we have two problems: log lines can be interleaved,
and rotation can cause a line to be split over two files. Triple ugh.
