Abstract
In an object-relocating garbage collector, objects are copied and new copies taken into use concurrently with mutator execution without needing to use a read barrier, and importantly, without requiring verification (read-back) of each copied word and without requiring atomic instructions for the copying. Write barriers, thread-local write barrier buffers and processing them by the garbage collector, and write propagation are used for achieving this.
