Seems to be the same or at least related.
On comment about my first mail: this is the correct code of condvars, despite what I wrote before. I wasn't thinking clear. The internal futex is a normal futex. It is the job of the CMP_REQUEUE_PI call to figure this out, select the waiter with the highest priority, and boost the priority if necessary based on the targer futex which always is a PI futex.
