 	Yes, the right thing does happen.

-**8**. Now let’s look at the code in peterson.s, which implements Peterson’s algorithm (mentioned in a sidebar in the text). Study the code and see if you can make sense of it. 
-
-**9**. Now run the code with different values of -i. What kinds of different behavior do you see? Make sure to set the thread IDs appropriately (using -a bx=0,bx=1 for example) as the code assumes it.
-
-**10**. Can you control the scheduling (with the -P flag) to “prove” that the code works? What are the different cases you should show hold? Think about mutual exclusion and deadlock avoidance. 
-
-**11**. Now study the code for the ticket lock in ticket.s. Does it match the code in the chapter? Then run with the following flags: -a bx=1000,bx=1000 (causing each thread to loop through the critical section 1000 times). Watch what happens; do the threads spend much time spin-waiting for the lock? 
-
-**12**. How does the code behave as you add more threads? 
-
-**13**. Now examine yield.s, in which a yield instruction enables one thread to yield control of the CPU (realistically, this would be an OS primitive, but for the simplicity, we assume an instruction does the task). Find a scenario where test-and-set.s wastes cycles spinning, but yield.s does not. How many instructions are saved? In what scenarios do these savings arise? 
-
-**14**. Finally, examine test-and-test-and-set.s. What does this lock do? What kind of savings does it introduce as compared to test-and-set.s?
