This is a fine thing to do. But the function name is less than
informative. I think I would call it something like `dup_cloexec'.
The use of the term `helper' here is particularly confusing because it
also refers to the `save helper' of which this is part.
And
- missing newline after the /*---*/ comment
- this function should have a doc comment saying it cannot fail
