55*0Sstevel@tonic-gate  * Delay the output for ms milliseconds.
56*0Sstevel@tonic-gate  * Note that this is NOT the same as a high resolution sleep.  It will
57*0Sstevel@tonic-gate  * cause a delay in the output but will not necessarily suspend the
58*0Sstevel@tonic-gate  * processor.  For applications needing to sleep for 1/10th second,
59*0Sstevel@tonic-gate  * this is not a usable substitute.  It causes a pause in the displayed
60*0Sstevel@tonic-gate  * output, for example, for the eye wink in snake.  It is disrecommended
61*0Sstevel@tonic-gate  * for "delay" to be much more than 1/2 second, especially at high
62*0Sstevel@tonic-gate  * baud rates, because of all the characters it will output.  Note
63*0Sstevel@tonic-gate  * that due to system delays, the actual pause could be even more.
64*0Sstevel@tonic-gate  * You can't get a decent pac-man game with this routine.
