docs: If a typechecking profiler is active, e.g. created by
      pytypes.set_global_typechecked_profiler(), such a profiler
      must be restored whenever a TypeCheckError is caught.
      The call must stem from the thread that raised the error.
      Otherwise the typechecking profiler is implicitly disabled.
      Alternatively one can turn pytypes into warning mode. In that
      mode no calls to this function are required (unless one uses
      filterwarnings("error") or likewise).
