    Problem Summary TSD4C.00199 This test may fail on implementations which do not have time to disable their signal handler before expect sends the interrupt character after a Control-V.
    Problem Text
    The test may fail on implementaions which do not have much time to
    recognize the Control-V before Expect sends the KILL character.
    Because of this, shell had received KILL character as control code
    on our implementation.

    For example, sh 91 test case executes following scenario after invoking
    sh -o vi:
    #Try Kill
    send "echo 'abc${ControlV}${Kill}def' >> tmp_91_1.out\r"

    Since sh processes ${Kill} character as Kill control code, sh assumes that
    input line is deleted at this moment, and then accept "def'" characters
    afresh. Since only one single quotation(') was inputted, sh waits for next
    single quotation being inputted. As a result, it occurrs test suite to be
    hanging.

    On our implementations, when manually typing "Ctrl+V" "Ctrl+U" characters
    from keyboard after invoking sh -o vi command, system normally displays
    '^U' character. For example, executing following first two columns will
    display the character '^U' shown in the third column:

    %sh -o vi
    $echo 'Ctrl+V Crtl+U' | cat -v
    $^U

    This indicates deficiency of VSC Test Suite.
