Review comment:
Since @Joscorbe asked for a second opinion. I could imagine passing a
thread-factory (could be a BiFunction<BackgroundUpdateOperation, String>) into
a new `DocumentNodeStore` constructor. That way the tests could pass in a
suitable factory and keep a reference to the thread and
`BackgroundUpdateOperation` to be able to accomplish the desired behaviour.
IMHO that would be more elegant, but that, as always, is in the eye of the
beholder.
