Minor Description
In an infinite loop try to add nodes one under another to have N0/N1/N2...NN. At some point, the current parent node will not be found and the current commit will fail. I think this happens when the path length exceeds 1000 characters. Is this enough for a path? I was able to create this way only 222 levels in the tree (and my node names were really short N1, N2 ...)
There's an automated tests for this: NodeExistsCommandMongoTest.testTreeDepth
