This issue arose because, apparently, we did get a split brain once upon a time. The hints I've got however are that this happened in a pre-3.5 version of Zookeeper, involving a (botched?) rescaling from 3 to 7 nodes. From which hints I'm guessing that something got fixed in 3.5 so that this approach to deliberately provoking a split brain would not work with the 3.5.7 we're now using.
