that has to be defined. But how can you test the child gets the correct
stdout ? either the child knows (by other ways) what stdout really is
(a file...) and can test it, either it doesn't care to know, and let
the parent check what the child just wrote. Again, stdout has not
to be used as a generic way to pass all information back to parent, 
just the stdout inheritance.
