That's right. Some kind of yield() should work.
I am using the boost threads interface, so Ken suggested their yield() method.
I presume there's a pthread version under the covers somewhere, but
have not studied how boost handles Linux threading.
I might experiment with it some more later, but it's working OK right
now and I don't want to make unnecessary changes now with Diamondback
beta out.
