It happens in AlphaLiveProcess. I had the inclination that EIO is only Alpha capable, I think I saw it on our wiki. Is that inherent or just the way it is because we just don't have it for something else? I'm not sure we'll develop eio for non-alpha anyway. But if people object, let me know, I had an alternate fix that resides within the AlphaTLB only.
