bdea0d4 by Guy Harris (guy@xxxxxxxxxxxx):

    Check for ECHILD, not for "not ECHILD".
    
    That makes the logic a bit clearer (and puts the "unexpected other
    error" case at the end, where it should be).
    
    Put all the errno checks inside an else clause, making it clearer that
    it runs only if waitpid() returned -1.
    
    Add comments, including comments explaining why just driving on after
    getting EINTR should be OK.
