I still utterly detest that this adds a second hash-table for no descernable reason. The new syscall interface does not depend on that in any way, you previously implemented the multi-wait thing in the current futex code. Like I said last time; I'm okay with the new interface, but I don't see why you need to reimplement the insides, that's all pointless code duplication.
