Many thanks kind monk, that certaintainly did solve the problem. Not only that it runs twice as fast. Well OK maybe that's an exaggeration, but it's a lot faster.

The only problem seems to be that it doesn't exit when the queue is empty. Does $running perhaps need to be modified inside the loop? I'm not sure because I don't really understand how the statement $running : shared = 0; works. Is the colon a conditional operator or does it tie $running to something in threads::shared?
