improved benchmark experience on Windows

Browse Source 
benchmark results are not progressively displayed on Windows terminal.
For long benchmark sessions, nothing is displayed,
until the end, where everything is flushed.

Force display to be flushed after each update.
Updates happen roughtly every second, or even less,
so it's not a substantial workload.
