You must perform a yielding operation periodically that allows your app to
give up the rest of its CPU timeslice so that other apps can have a chance
to use the CPU.  Something as simple as a call to Sleep() with a timeout
between 0-10 ms will usually do the trick.

That depends on the amount of message traffic you have.  If you have a lot
of pending messages, then it may or may not yield right away.

If you don't care about the messages, then use Sleep() in the loop.
Otherwise, you should move the code into a worker thread and let the main
thread handle its messages normally.
