> The more content is read below a given location the more expensive the getStatus() becomes
on that TreeLocation. There seem to be two issues:
> - Reading creates snapshots in MemoryNodeBuilder depending on how the tree is accessed.
> - Cost for comparing states also increases as snapshots are created for NodeStates.
> I'll attach a test that shows the described behaviour.
