Doing flush after each output operation does carry a performance penalty.

The example is of course written to emphasise the issue.

? default implicit_flush to isatty(stdout) should help here?

This may be a great idea. There is cons also. Users may be looking the file with tail... We are better to have ability enable/disable implicit flushing at user's will. -- Yasuo Ohgaki
