Not sure about your specific question, but the piece I quoted only
unbuffers stdout and stderr, so that output sent on both file handles
do not get printed out of order (in other words, if we print on
stderr first, and then stdout, we want the output to be in that
order - with buffering, we observed that stderr output was printed
after stdout output, even if the actual call to printf was in a
different order).
