Dr. Dobb's | Eliminate False Sharing | May 14, 2009: "false sharing (aka cache line ping-ponging), where threads use different objects but those objects happen to be close enough in memory that they fall on the same cache line, and the cache system treats them as a single lump that is effectively protected by a hardware write lock that only one core can hold at a time."
