/**
* Interface for observers wanting to be notified of incoming FreeSWITCH Event Socket events.
* <p>
* Incoming events arrive asynchronously and are processed into two queues, one for server
* initiated events, and one for the results of client requested background jobs.
* <p>
* Each queue is serviced by a different thread pool (to ensure lowest latency for event-driven events)
* and each queue is guaranteed to be processed (and listeners notified) in the order in which the
* events are received off the wire.
* <p>
* This design ensures that incoming event processing is not blocked by any long-running listener process.
* However multiple listeners will be notified sequentially, and so one slow listener can cause latency
* to other listeners.
