> LoadGenerator#genFile's write close timing code looks like the following:
> {code}
>         startTime = Time.now();
>         executionTime[WRITE_CLOSE] += (Time.now() - startTime);
> {code}
> That code will generate a zero (or near zero) write close timing since it isn't actually
closing the file in-between timestamp lookups.
