> In this scenario when peek() is called from BucketRegionQueue, a side effect 
> is that the key is removed from the eventSeqNumQueue and an event is placed 
> into the peekedEvents list.
> If there is failure dispatching the event, we add the peekedEvents list to a 
> new peekedEvents list.  Before doing so, we remove any events that we are not 
> primary for.  Now the event is not in the eventSeqNumQueue or the 
> peekedEvents list
> If we now become primary (before the other node could dispatch this event), 
> and because we do not have that event in the eventSeqNumQueue or the 
> peekedEvents, it gets "stuck."
