This had more to do with small blocks in CFG being merged into one than 
with the selects themselves.  I can't post any original sources, and it 
would take me some effort to regenerate the situation, so I can't 
promise that I will be able to do it.  If I run into something that I 
can post here, I will (if I don't forget).
