C-CEX is waiting for us to give them green light to upgrade.

I want to ensure the ReadBlockFromDisk error is Dead before I green light them.

Overnight, I made an update internally to the pool server with new code.  Now I am burning it in. 
We will have to wait until I have time to parse the logs and ensure the error is dead.
