> In some cases DocumentNodeStore.rebase(NodeBuilder) can be expensive when a
> node is added to a parent that already has many children.
> There are a few other conditions that also need to be met to make the refresh
> expensive. Steps to reproduce are:
> Create a node structure with many child nodes and save
> Create a sibling to those many nodes, but not yet save
> Make further transient changes until the DocumentNodeStore creates an
> InMemory branch. A test can also force create this branch.
> Add further changes to the new node
> Rebase the current builder. Now the implementation reads all siblings of the
> new node, while it should only check if the added node already exists.
