multi api: This is known to be the fastest api but also a little trickier with handling responses properly. It also only succeeds if all of the individual operations succeed. You can use a multi to only write data if a certain znode has a given version as another use case.

We should ensure the ZooKeeper information present to clients is not inconsistently out of date as much as possible. Waiting to see the collection state change and getting the latest state but very stale live nodes is not a good situation.
