public class StaleEvent
Generic event denoting that the state of an IObservable object is
about to change. Note that this event is only fired when an observable
becomes stale, not when it becomes unstale; an observable that becomes
unstale should always fire a change event. Staleness can be used (for
example) to notify listeners when an observable has started a background
thread for updating its state. Clients can safely ignore staleness.
