Summary: This is inspired by debugging a regression test that runs for ~0.05 seconds and the short running time makes it prone to variance. While db_bench ran for ~60 seconds, 59.95 seconds was spent opening 128 databases (and doing recovery). So it was harder to notice that the benchmark only ran for 0.05 seconds. Normally I add output to the end of the line to make life easier for existing tools that parse it but in this case the output near the end of the line has two optional parts and one of the optional parts adds an extra newline.
