  // #1 is always an error. At best the caller is leaking memory briefly in something like an
  // AsyncTask. At worst the caller is leaking an Activity or Fragment for a sustained period of
  // time if they do something like reference the Activity RequestManager in a long lived
  // background thread or task.
  //
  // #2 is always an error. Callers shouldn't be starting new loads using RequestManagers after
  // the corresponding Activity or Fragment is destroyed because retaining any reference to the
  // RequestManager leaks memory. It's possible that there's some brief period of time during or
  // immediately after onDestroy where this is reasonable, but I can't think of why.
