Actually I'm not sure about flushing. I thought of the case
such that I'm sending a string packet over a pipe or socket, and
want to make sure I send entire string, without worrying that the
last few characters might be sitting in the character conversion
But I might be able to achieve it by creating and closing a
stream each time I want a complete "packet". Though it
seems to me lots of overhead, it may be doable.

Or passing special value (e.g. #f) as "bytes"?
