This works now, but it makes me worry. I think that the symbolic
execution framework doesn't really cope very well with mutable
objects; I expect that we'll get other problems like this.
I wonder if you or Armin have a better idea on how to deal with this?
I'd think that maintaining a 'changed-since-last-clone' flag in each
object seems a pretty ad-hoc solution...
