Yes. I'll benchmark how much overhead is added by the calls to flush; there's no point in breaking the abstraction boundary of BufferedWriter if it doesn't give a significant performance benefit. (I suspect that it might not, because Windows is very slow at scrolling a console, which might make the cost of flushing insignificant in comparison.)
