Description

As of 3.4.3 Zookeeper now has full, multi-operation transaction. This means we can wholesale delete chunks of the zk tree and ensure that we don't have any pesky recursive delete issues where we delete the children of a node, but then a child joins before deletion of the parent. Even without transactions, this should be the behavior, but it is possible to make it much cleaner now that we have this new feature in zk.
