A method of rescinding ownership of a cache line in a computer system includes constructing a table of caching agent representations in which each caching agent representation is accompanied by a validity indicator. The method continues with receiving a cache line sharing list, with each entry of the cache line sharing list indicating the potential ownership of the cache line by one or more caching agent representations that correspond to an entry of the sharing list. The method also includes conveying a snoop packet to a caching agent when the logical conjunction of an entry of the cache line sharing list that corresponds to a caching agent representation and the accompanying validity indicator meets a predetermined Boolean condition.
