serializers are inherited. Streams can't be removed as part of the child creation. The child doesn't own the parent's streams (so can't close them). - Clean up Logger creation. The goal here was to ensure `log.child` usage is fast. TODO: measure that. - Add `Logger.stdSerializers.err` serializer which is necessary to get good Error object logging with node 0.6 (where core Error object properties are non-enumerable).
