-** User function W: exit, sleep, write, getpid, gettime

-** Reports its presence, then iterates 'n' times printing identifying
-** information and sleeping, before exiting.
-**
-** Invoked as: userW x [ n [ s ] ]
-** where x is the ID character
-** n is the iteration count (defaults to 20)
-** s is the sleep time (defaults to 3 seconds)
