I am not sure why ZOOKEEPER-1810 introduced separated thread. But there are do differences in behavior in logging(jdk System.err vs slf4j LOG.info).
I am good to the direction. Also, it will supersede ZOOKEEPER-4884.

WorkerSender inherits from ZooKeeperThread. When using WorkerSender, a WorkerSender thread is created first, followed by the creation of a new thread where WorkerSender is passed as a task. At this point, the ExceptionHandler in ZooKeeperThread does not take effect.
