  "message": "Spin SpinLock for a fixed duration rather than a fixed iteration count.\n\nA fixed spin-loop iteration count spends about 2× more wall-clock time on slower CPUs than on faster ones.\n\nOn first contention, time the spin loop and convert a 500 ns target into an iteration count using CycleClock::Frequency(), spinning at least 500 iterations.\n\nPiperOrigin-RevId: 1015592590\n",
