From: Paulo Zanoni <paulo.r.zanoni@xxxxxxxxx>
I often run "sudo ./test 2>&1 | tee output.txt", and when we're
succeeding - never printing to stderr - the output gets buffered and
is never flushed (because it doesn't point to a terminal), so I never
know which test is running. With this fflush, I'm able to know when
each test finishes.
