In this type of lock, readers and writers alternate. This significantly reduces the worst-case blocking for readers and writers. This is an implementation derived from FreeBSD based on the work described in: Brandenburg, B. and Anderson, J. 2010. Spin-Based Reader- Writer Synchronization for Multiprocessor Real-Time Systems All locks must be initialised before use, and only initialised once. Definition in file rte_pflock.h.
