    Fix select()/kqueue() bug with pipe()s
    
    * This causes select() / kqueue() was not returning a writable condition
      on a pipe() whos other end was closed early.
    
      If a select/kqueue test is performed prior to the other end closing,
      then future calls will later properly detect when the other end closes.
    
    * Should fix numerous niggling issues, including csh sometimes failing
      to recognize early exits of children.
