        Patch from Jeffrey Stedfast <fejj@ximian.com> (#104825)

        * glib/gspawn.c (read_data): Don't read() into '&buf', while this
        is technically okay - it is clearer as just 'buf'.
        (write_all): New helper function that handles write() interrupts.
        (write_err_and_exit): Use write_all() instead of write().
        (fork_exec_with_pipes): Same here.
