I've created a new class called LeaveClusterRequest. This request is sent over the cluster when PostOffice.stop is called. I have added a parameter boolean to stop, when if you set it to false it will emulate a crash. Now... viewAccept will perform a failOver if a view is changed. I still need to add some logic to have only one server accepting the failOver but that is pretty easy. I will do it probably over the holidays.
