@kuhar, I have not looked at the DTU uttility yet, but I'd think it can be rewritten (unless there are some limitations for the DomTreeUpdater utility). However, that would be a large enough change and I think it's better to do it as a separate change at a later point rather than as part of fixing this bug. Also, there are enough DT updates through out this code that it will take a while to get through the whole process of porting over for runtime unrolling.
