To be honest, I'm still trying to parse this last sentence.

Working harder won't help.  I just need more time to think about this.  I 
don't know if you saw the documentation and code required to deal wih this 
issue in version 1.32 but it was very messy.  I invested effort which I 
believe resulted in a major improvement.   So far no one has come upon this 
in practice and I'm curious to know why that might be.
