There is an existing comment explaining this:
* The output is accumulated in a buffer and
* each line is printed to stderr using
* write(2) to ensure inter-process atomicity.
which seems reasonable to me (I know that write(2) does not guarantee to
write everything, but write_in_full() does not guarantee atomicity, as
far as I know).
