Answer 1

What's the issue with sleeping for a very brief period of time? 1 millisecond is close to an eternity to a modern computer. Provided you don't have thousands of these threads (which it sounds like you don't), then there is NOTHING wrong with sleeping for one, ten, ten thousand, or ten million milliseconds every iteration through the loop. The CPU won't even notice this little blip.
