Hmm... not much good using a fork designed to increase the max blocksize limit if you can't... increase the max blocksize.
It's a p2pool bug, not a Classic bug.
I don't recall saying it was a classic bug anywhere... but I understand your desire to pop up here and defend classic in that way.
You can increase the max block size limit, just not the soft limit when mining with p2pool.
You overlooked that these are two different things in your urgent need to snark.
