These should be CamelCase, and I have an idea to get rid of `num_inseparable_spaces`. If we make `_claimed_index` an integral type we could define `EdenIndex = -2` and `SurvivorIndex = -1`. If we then initialize `_claimed_index = EdenIndex` the old gen indices will be correct without needing a decrease. ------------- PR: https://git.openjdk.java.net/jdk/pull/25
