ABSTRACT:
A queue-based spin lock with timeout allows a thread to obtain contention-free mutual exclusion in fair, FIFO order, or to abandon its attempt and time out. A thread may handshake with other threads to reclaim its queue node immediately (in the absence of preemption), or mark its queue node to allow reclamation by a successor thread.
