I believe your idea to use futexes is far better than using eventfd for dealing with a large number of calls or events.

However I think the existing Futex API allows implementing wait-for-multiple-events with great performance. I have good experience implementing such functionality with existing APIs, and know of no conceptual restrictions there. See also my slightly more detailed comment above.
