> MemoryNodeStateBuilder inefficient for large child node lists
> -------------------------------------------------------------

> Key: OAK-175

> OAK-174 leverages the {{getChildBuilder()}} method introduced with OAK-170.
> This revealed a performance issue for large child node list with the
> {{MemoryNodeStateBuilder}} implementation: without additional measures (see
> below) {{RootImplTest.largeChildList()}} is very slow.
> The additional measures I currently implemented consist of counting the
> overall number of changes to a tree and purge these down to the branch when a
> certain threshold is reached. See {{RootImpl.purge()}}. However, I think this
> mechanism is too ad-hoc and we should find a more general solution.
