> It looks like when shutting down Broker, the listener sticks around for an exceptionally long time (as much as a minute or more). Because of this, Broker's listener actually fails to re-bind to the port on the next cluster start silently. All Broker communication then fails to work silently. It can take a while to notice this failure, since nothing really complains. 
> The listener should probably shut down faster than 1 minute... but it might also make sense to add options to have the listener retry to start, or generate a failure message when it doesn't start. Maybe listener starts in bro_init should actually cause Bro to stop, so that the user sees the failure immediately?
