I don't need the filesystem fixed, it's fairly quick for me restore it, but obviously if there is any useful state in it for improving the code, that will be lost. I understand it's the weekend, if someone thinks I should wait until monday to give some other folks the chance to see/reply, let me know, and I'll keep my system down until monday.
