I think it does... you just need to wait for it.
You didn't wait long enough ;-)

Call io__flush_output after io__write, or ensure that the output is
terminated by a newline (or both).  Otherwise the output will only make
it to the terminal when the output buffer fills up, which at the rate
of about 10 characters output per second (due to all those calls to "sleep")
will probably take quite a few minutes.
