         The pipeline state can be persisted to the disk, allowing it to be resumed later.
         It is a Python Iterable, but it also contains the iterator states.
-        Calling `iter` a second time while the first iterator is still being used
-        will segfault or worse.

+        and sharing the same state, so it will behave inconcistently.
