I don't understand this issue.
Is any user code modifying this list? Concurrent read access should be well
possible with any regular list.
The system never modifies the list after it has been created once.

> We should provide a simple utility method for zipping elements in a data set
> with a dense index.
> its up for discussion whether we want it directly in the API or if we should
