For this exact test, calling req.write a thousand times is actually
slower (though only by a factor of two or so). If we were being really
minimal:
req.write("Yeah\n"*1000, 0)
comes in at about a quarter again as fast as the buf version. But
clearly 'benchmarks' on this kind of level aren't really useful, just
needed to point out the difference between sending response to client
in lots of teeny bits vs. one finished chunk.
