FCFS RWLock is a Readers/Writers Lock (or RWLock for short) is a mechanism that allows an arbitrary number of readers or alternatively one writer to access a resource at any given time. FCFS RWLock project is useful in case writing may temporarily harm the integrity of the resource. Many RWLock implementations arbitrate the various readers and writers in a manner that may cause starvation of either readers or writers. For instance, a readers/writers lock that prefers readers may cause a writer to starve (i.e: wait for a very long time or indefinetly) if there are two and more competing readers. A First-Come First-Served (FCFS) RWLock solves this problem by making sure that the pending threads are served at the same order as the time of their arrival. Thus, starvation is eliminated assuming that a thread does not obtain the lock indefinetly (which in any case should not happen in a well-designed system)..
