I could (and might, too), but unfortunately (well, I guess...) I  
haven't been able to reproduce this, despite writing a script to  
really stress test it. It's either pretty darn random, or I was simply  
wrong about the rollback being involved. I've only gotten it once  
since I started using -CURRENT in early May(?) so I don't think I  
could tell whether the patch helps or not. :(

Thomas
