Queue-based spinlocks allow programs with busy-wait synchronization to scale to very large multiprocessors, without fear of starvation orperformance-destroyingcontention. Timeoutcapable spin locks allow a thread to abandon its attempt to acquire a lock; they are used widely in real-time systems to avoid overshooting a deadline, and in database systems to recover from transaction deadlock and totolerate preemption of the thread that holds a lock. In previous work we showed how to incorporate timeout in scalable queue-based locks. Technological trends suggest that this combination will be of increasing commercial importance. Our previous solutions, however, require a thread that is timing out to handshake with its neighbors in the queue, a re...
