A Fast Mutual Exclusion Algorithm

This is aliveness property, which can be proved formally using temporal logic— for example, with the method of Owickiand Lamport[9]. However, only an informal sketch of the proof will be given.

Since Chandy and Lamport's seminal paper on this topic, this problem is called the snapshot problem. Unfortunately, the lack of both a globally shared memory and a global clock in a distributed system,
