-----------------------------------

[~szetszwo] I'm thinking TransferLeadershipRequest should include a timeout 
field, server check whether the newLeader grap the leadership at a fixed rate 
before timeout. So maybe we need following scheduleAtFixedRate. What do you 
think ?

{code:java}
public ScheduledFuture<?> scheduleAtFixedRate(Runnable command,
                                                  long initialDelay,
                                                  long period,
                                                  TimeUnit unit) 
{code}
