| // Notice we set the old gen heap size to 12 MB, which seems to be the minimum |
| // (in debug mode) to not cause us run OOM during isolate initialization. The |
| // problem here is that we pre-allocate certain exceptions, e.g. NullThrownError |
| // during isolate initialization, but if we have an allocation failure before |
| // that, we end up running into a recursive allocate/throw loop. |
| // |
| // Test that compaction does occur on repeated add/remove. |
