It often arises from stringent policies that are used to avoid race conditions, and they are illustrated by the fact that the dining philosophers can't pick up enough utensils at the same time to start eating.
This phenomenon is present when a cycle is detected in a wait-for graph, where edges represent dependencies between units. One approach of avoiding this phenomenon makes use of a Boolean vector that manages "safe states" as well a resource vector that tentatively allocates a configuration called a sequence to jobs. A "hold and wait" policy is necessary for this to occur, and the ostrich algorithm in which you pretend there is nothing wrong is one way often used to deal with it because of its relative rarity. Synchronization solutions that cause circular wait lead to it, which is avoided by the banker's algorithm. It often arises from stringent policies that are used to avoid race conditions, and they are illustrated by the fact that the dining philosophers can't pick up enough utensils at the same time to start eating. For 10 points, identify this state of two or more concurrent threads or processes being unable to perform useful work.
