It wouldn't need to convert the whole Frameworks layer into C, just enough to manage the suspend state.
Anyway, I think there's been enough arguments against even the concept of opportunistic/auto-suspend, and I for one will object with a NAK if Rafael send this to Linus.
The whole idea of segregating userspace like that, and not letting runnable thing run is very ill considered indeed.
