> As NettyServerCnxn.sendResponse() allows all the exception to bubble up it 
> can stop main ZK requests processing thread and make Zookeeper server look 
> like it is hanging, while it just can not process any request anymore.
> Idea is to catch all the exceptions in NettyServerCnxn.sendResponse() , 
> convert them to IOException and allow it propagating up
