Thanks, Pete.

Sometimes I am so stupid.  The more obvious something is the less chance 
I have to notice it. I wrote something almost identical except I didn't 
set the seed EVERY time I got a value as I should, but only when I was 
switching threads.  When I realized that didn't work, my brain 
apparently threw out the whole concept...
