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.
