45 | * Weak reference: this object does not own it, and `trace` |

47 | * Instead, we add a "trace destruction" listener (in | |

49 | * trace object is destroyed. | |

50 | * |
51 | * Otherwise (with a strong reference), we would keep this trace | |
52 | * object alive until the upstream message iterator ends. This | |

54 | * to traces and streams which otherwise would not exist. | |
