hanm opened a new pull request #1007: ZOOKEEPER-3448" Introduce MessageTracker to assist debug
leader and leaner connectivity issues.
URL: https://github.com/apache/zookeeper/pull/1007
 
 
   We want to have better insight on the state of the world when learners lost connection
with leader, so we need capture more information when that happens. We capture more information
through MessageTracker which will record the last few sent and received messages at various
protocol stage, and these information will be dumped to log files for further analysis.
