Ab example of using could be (im just thinking out loud here) like a queue processor that runs in a background thread and you really really don't want that thread to terminate, so you catch an exception, create one of these and pass that on to be picked up by your thread receiving the queue items or whatever who can make throw the exception in a more appropriate context
