1. Initialize a string called "result" to the fractional part preceded with an "&"
2. Initialize an integer array called "number" of the digits of the number, from LSD to MSD
   (in your example, {9, 8, 7, ... 3})
3. Iterate through the digits in "number" to get the variables "curDigit" and "curDigitIdx"
4. Perform the following logic using curDigitIdx (the index in your array) and curDigit
switch (curDigitIdx % 3) {
    case 0:
        result = string.Format("{0}{1} {2}", digitNames[curDigit],
                 magnitudeNames[curDigitIdx / 3], result);
        break;
    case 1:
        result = string.Format("{0}{1}", tensDigitNames[curDigit], result);
        break;
    case 2:
        result = string.Format("{0} hundred {1}", digitNames[curDigit], result);
        break;
}

1. Create a shared boolean object initialized to false called "TimeToExit"
2. Periodically check the value of TimeToExit from the running thread.  If true, exit.
3. From the main thread, after setting TimeToExit to "True" and waiting for some amount
   of time without the thread ending (the maximum thread response time), kill the thread :(
