Although this is a standard conforming way to wait for a certain time
period, it is actually not a very friendly way on a multi-user system.
This loop probably consumes 100% CPU time while it is doing nothing.
For this kind of task, it is advisable to look for a implementation
specific method. Functions like Sleep (Windows) and sleep/usleep (unix)
come to mind.
