If you think it's possible to make this work then feel free to. But at
the point where you're adding code to every driver's suspend function to
determine whether or not it's got any pending events that userspace
hasn't consumed yet, and adding code to every bit of userspace to allow
it to indicate whether or not it's busy consuming events or just busy
drawing 3D bouncing cattle, I think you've reinvented suspend blocks.
