> When a Processor is unable to perform any work, it has the ability to
> "yield," or pause itself so that it does not chew up resources while it's
> unable to do anything useful. It appears, though, that even when a Processor
> is yielded, it uses a lot of CPU. Adding some logging shows that this is due
> to Processors continually checking if there is work to do, even when they are
> yielded. This can be improved.
