Put a string to an out range, which is normally a file
to an interactive terminal like /dev/tty or stdin, while
interpretreting embedded delay sequences of the form
$<DELAY> (where DELAY is given in milliseconds, and must
be a postive rational number of millseconds). When these
are encountered, the flush delegate is called (if not null),
and the function sleeps for the indicated amount of time.
