        * io/transfer.c (dta_transfer_init): Do not treat as an
        asynchronous statement unless the statement has
        ASYNCHRONOUS="YES".
        (st_write_done): Likewise.
        (st_read_done): Do not perform async_wait for synchronous I/O
        on an async unit.
        (st_read_done): Likewise.
