> The branch/merge features on the MicroKernel were initially introduced to
> stage changes of large commits. Currently oak-core creates a branch even for
> small changes like updating a property. I think this introduces quite some
> overhead for scenarios with highly concurrent updates. E.g. think of a
> twitter like application or a forum with comments. Well, basically user
> generated content. These update tend to be rather small (couple of nodes) but
> frequent and concurrent.
> Right now oak-core always does:
> - MK.branch()
> - MK.commit() to branch
> - MK.merge()
> For small commits, it ideally should do:
> - MK.commit() to trunk
