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.
