Your understanding of MVP is probably less limited than mine--I assumed it was a riff on MVC. Anyway, couldn't you design an MVP framework to include "I'm done paying attention to changes" events, and use onUnload to trigger them when the presenter is using a widget and use some other means when it's using something besides a widget?
