> Optimize KernelNodeState equality checks

> Key: OAK-172

> Much of our higher level functionality depends on efficient diffing of
> content trees. Our current algorithm for diffing KernelNodeStates depends
> heavily on the performance of the equals() method. Currently equals() does a
> full tree comparison, but we can shortcut that in most cases by using the
> ":hash" pseudo-property from the underlying MicroKernel.
