* work on all systems. It is included in curses to provide a portable

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