> We allow IsisInteractions to be nested. The @IsisInteractionScope is always bound to the top-level IsisInteraction of the current thread's session stack. (first stack element, aka bottom of stack) 
> Isis (not Spring) is aware, when any IsisInteractionScope ends. So at the end of each IsisInteractionScope, we call the destruction runnables on the IsisInteractionScope-d beans that belong to the current thread, then clear the IsisInteraction stack (of the current thread). (edited) 
> The IsisInteractionScope-d beans are managed by Spring, that is Spring creates them and registers their destruction runnables.
> Requires Provider idiom: we fail early if one tries to inject an IsisInteractionScope-d bean directly. The thrown exception gives a hint, how to fix it. (Use the Provider<> idiom instead)
