@Retention(value=RUNTIME)
@Scope

public @interface ConcurrentSingleton

Apply this to implementation classes when you want only one instance (per Injector) to be reused for all injections for that binding, and you want to eagerly create the instance concurrently in the background with other singletons in this scope.
