Thanks, StackToRegisterMappingCogit is really impressive. IIRC for the 
4.1.1 VM Andreas fixed something about ImageSegment loading which is 
missing from the CogVMs. It would be good to have that fix, because now 
arrayOfRoots is nil when I'm trying to load an ImageSegment. It's not 
urgent at all, because I could work the problem around using the new 
SqueakVMs which can read Cog images and have the fix.
