Description

ZK supports asynchronous modes and we are only using the synchronous mode
However there is an asynchronous version of getData()

  /**
     * The asynchronous version of getData.
     *
     * @see #getData(String, Watcher, Stat)
     */
    public void getData(final String path, Watcher watcher,
            DataCallback cb, Object ctx){
}

should we run tests to compare if it can give us an advantage? I guess it should

Another optimization is doing multiple deletes from the workQueue using the following method

 /**
     * The asynchronous version of multi.
     *
     * @see #multi(Iterable)
     */
    public void multi(Iterable<Op> ops, MultiCallback cb, Object ctx) {
 }
