Oh, I argued against it. And I told people we can always revert it. But even better than reverting it is to just fix it cleanly in the new world order, wouldn't you say? > So to answer your question, I guess I would like to know a bit > more about the regression and what the app is doing. Ok, go ahead and try to figure it out. But please don't cc me on it any more. I'm not interested in your hang-ups with ZERO_PAGE. Because I just don't care. I think ZERO_PAGE was great to begin with, I put it to use muyself historically at Transmeta, and I didn't like your crusade against it. People (including me) have told you why it's useful. Whatever.
