Editing Mutual exclusion (section)

==Recoverable mutual exclusion==
Most algorithms for mutual exclusion are designed with the assumption that no failure occurs while a process is running inside the critical section. However, in reality such failures may be commonplace. For example, a sudden loss of power or faulty interconnect might cause a process in a critical section to experience an unrecoverable error or otherwise be unable to continue. If such a failure occurs, conventional, non-failure-tolerant mutual exclusion algorithms may deadlock or otherwise fail key liveness properties. To deal with this problem, several solutions using crash-recovery mechanisms have been proposed.<ref>{{Citation | chapter-url=http://dl.acm.org/citation.cfm?doid=2933057.2933087 | last=Golab|first=Wojciech|author2=Ramaraju, Aditya | title=Proceedings of the 2016 ACM Symposium on Principles of Distributed Computing|chapter = Recoverable Mutual Exclusion|date = July 2016| pages=65–74| doi=10.1145/2933057.2933087| isbn=9781450339643| s2cid=8621532}}</ref>
