Normally we try to reduce our C++ content, but the complexity's much lower here since we can't use Swift's atomics properly on Darwin yet and since we don't need to juggle Swift module visibility.

  • Code and documentation should follow the style of the Style Guide.
  • If public symbols are renamed or modified, DocC references should be updated.
