I can only echo Mels comments here. It is very hard to review such a large patch which mostly is fixing a very small change. This code is pretty fragile and would need significant testing, I don't know if Mel is able to run the same tests we used when putting this together in the first place. By the looks of the rest of the thread Kame-san is going to break this up so I'll wait for that. Thanks! -apw
