> This provides a way of sending exceptions from 'external' threads/processes (not the main executing thread) to others that poll cooperatively for external exceptions.  Some examples of how this can be used include: having a separate timeout thread that injects an exception when a time limit has elapsed (TimeoutExceptionInjector, was OperationAttemptTimer), or having an exception from an separate process delivered to a local thread.  
> This simplified version is centered around the ExternalException class.  Instead of using generics and ErrorListener interfaces, this more straight-forward implementation eliminates many of the builders/factories and generics.
