EVALUATION Class ChunkData holds a number of fields used by par compaction to track where a contiguous range of gc-managed memory will be copied, among other things. An upcoming change will add an additional data structure that refers to smaller contiguous ranges of memory, likely to be called blocks. The term region is preferable to chunk since the size of a chunk vs. that of a block is ambiguous, while in common usage (e.g., maps) a region is larger than a block.
