If it checks cache local to the build tree, then I have no idea. I just run the validation and 
don't touch the tree until validation ends. If it checks the global cache in ~ then I have a 
suspicion of what might have happened - will check that.

Thanks Ian, I will keep that in mind and try to investigate the problem when it happens again.
