There's no mention of FUTEX_REQUEUE, and no mention of the important token-passing property: that the value returned from FUTEX_WAKE is equal to the number of calls which return 0 from FUTEX_WAIT. (Only when FUTEX_FD is not used; FUTEX_FD is broken with respect to token passing at the moment). -- Jamie
