Adding slot_hits + slot_displacements in RFC 005 grew SchedulerStats from 16 to 32 bytes — exactly 2 per cache line. run_queue_len (written on every push/pop by thread N) then false-shared with fields of thread N+1, causing ~45-60% yield-storm regression at t≥8 visible equally in slot-on and slot-off paths.
