+ * TestJoin is a simple application used to test the basic functionality of
+ * the join() system call for waiting on a set of threads in a TOSThreads 
+ * based application.
+ * 
+ * Upon a successful burn, you should see all LEDs toggle in the following pattern,
+ * repeating every 8 seconds:
+ * 
+ * 0s: (110) LED0  ON, LED1  ON, LED2 OFF  <br>
+ * 1s: (000) LED0 OFF, LED1 OFF, LED2 OFF  <br>
+ * 2s: (010) LED0 OFF, LED1  ON, LED2 OFF  <br>
+ * 3s: (000) LED0 OFF, LED1 OFF, LED2 OFF  <br>
+ * 4s: (111) LED0  ON, LED1  ON, LED2  ON  <br>
+ * 5s: (001) LED0 OFF, LED1 OFF, LED2  ON  <br>
+ * 6s: (011) LED0 OFF, LED1  ON, LED2  ON  <br>
+ * 7s: (001) LED0 OFF, LED1 OFF, LED2  ON  <br>
