> The code that closes down a ZKW that fails to initialize when attempting to 
> connect to the remote cluster is not MT safe and can in theory leak 
> ZooKeeperWatcher instances. The allocation of a new ZKW and store to the 
> reference is not atomic. Might have concurrent allocations with only one 
> winning store, leading to leaked ZKW instances.
