    Problem Summary Test program using the wrong file descriptor as select
    parameters
    Problem Text The test program is prepared to test select(). According to the
    specification, the second parameter of select() is readfds:

    "If the readfds argument is not a null pointer, it points to an
    object of type fd_set that on input specifies the file
    descriptors to be checked for being ready to read, and on
    output indicates which file descriptors are ready to read."

    The test program use ?FD_SET(fildes[1], &readfds);? to add
    fildes[1] to readfds. But the file descriptor fildes[1]?s flag
    is O_WRONLY|O_NONBLOCK. We thought we need to add a file
    descriptor which have the read flag to readfds such as
    fildes[0].
