Hi Peter,

This certainly avoids the overflow issues, but I think much of Sherman's concern 
is over the clarity of the code. I'm not sure that we're so concerned about an 
additional field in the spliterator instance that we'd steal a bit from 

Still, I'll link this thread to the new bug to make sure it doesn't get lost.
