I had a look into implementing a Watch in the case where we get a NOAUTH
error when trying to create the ephemeral node. The plan was that when the
parent node ACL was modified that the watch would fire and we would retry.
Unfortunately it seems that ACL changes in ZK don't fire Watches (I wasn't
aware of this), so there doesn't seem to be a way to reliably know when the ACL
changes without doing some sort of polling which is pretty ugly.
