Don't exit earlier from aspiration window loop Currently we exit the loop when abs(bestValue) >= VALUE_KNOWN_WIN but there is no logical reason for this. It seems more natural to re-search again with full open window. This has practically no impact in most cases, we have a 'no functional change' running 'bench' command.
