Unassigning myself as there is no plan to resolve this anytime soon.

> {{MicroKernel.rebase}} currently specifies: "addExistingNode: A node has been added that is different from a node of them same name that has been added to the trunk."
> This is somewhat troublesome in the case where the same node with different but non conflicting child items is added concurrently:
> {code}
> f.add("fo").add("u1"); commit();
> f.add("fo").add("u2"); commit();
> {code}
> currently fails with a conflict because {{fo}} is not the same node for the both cases. See discussion http://markmail.org/message/flst4eiqvbp4gi3z
