> In order to improve the performance of compareAgainstBaseState, it would help 
> to parallelize the recursive usage of compareAgainstBaseState. The idea is 
> that each sub tree which has a different revision would then be processed in 
> parallel (although it would probably suffice to only fork the process when 
> the nodes are not cached). This should significantly reduce the time which is 
> lost while waiting for an external database assumed that there are at least 
> two changes between the base revisions.
