 /**
+ * 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 LED2 toggles at the end of each time
+ * period. In addition, during each time period, LED0 should toggle twice, and LED1
+ * toggles four times (with an interval of 1 sec). This LED behavior repeats in the
+ * next time period.
