Right now CopiedSpace and MarkedSpace have the same block size and share the same regions, but there's no reason that they can't have different block sizes while still sharing the same underlying regions. We should factor the two "used" lists of regions apart so that MarkedBlocks and CopiedBlocks can be different sizes. Regions will still be a uniform size so that when they become empty they may be shared between the CopiedSpace and the MarkedSpace, since benchmarks indicate that sharing is a boon for performance.
