Consider the following implementation of a reusable barrier. When put in use, N processes will be executing the barrier code in a loop expecting to rendezvous at some point after the first line, and before entering the critical section For (global) initial values: # rendezvous count 0 mutex.waitO count +1 mutex - Semaphore(1) turnstile1- Semaphore (O) turnstile2 Semaphore (0) if countN: mutex.signal) turnstile1.wait() turnstile1.signal () turnstile1.signal () # critical section mutex.waitO count-= 1 if count 0: turnstile2.signal () mutex.signal O turnstile2.wait() turnstile2.signal() 1. Upon testing this implementation, we find that it only works a limited number of times. In the long run, processes are no longer forced to rendezvous before proceeding through the turnstiles. Why is this happening? 2. Show how you would fix the problem - make additions/alterations as needed to the code. Consider the following implementation of a reusable barrier.
