It is described, among other places, in "The Garbage Collection Handbook: The Art of Automatic Memory Management", by Richard Jones, Antony Hosking, Eliot Moss. In fact, they also call it buffered reference counting. Section 18.2: Buffered Reference Counting: "...DeTreville[1990] had log mutators the old and new referents of each pointer update to a buffer" By the way, this book describes a ton of other ideas to speed up reference counting in general and in the concurrent case, so it may be worthwhile to get it. I should warn you that many of these advanced refcounting ideas have been proposed in the past already, although I am unaware of this particular technique having been implemented. Stephan
