Quite. The first few days of any problem diagnosis are often a process of taking something from 'oh my god it might be the end of the world' to 'oh look it's really obscure, no wonder nobody has ever seen it before'. This is quite *definitely* such a problem. > It's a little bit too early for this meme: > > http://memegenerator.net/instance/28936247 It appears I have taken up a new post as the Iraqi Information Minister. This is why I was disturbed to see the thing hitting Phoronix and then Slashdot: as the guy whose FSes are being eaten, this is probably not an easy bug to hit! If it hits, the consequences are serious, but it doesn't seem to be easy to hit.
