8. Consider the following solution to producer/consumer problem. void producer(void) { int item; while(TRUE) void consumer(void) { int item; while(TRUE) { item=produce item(); P(&empty); P(&mutex); insert item(item); V(&mutex); V(&full); } } P(&full); P(&mutex); item-remove item(); V(&mutex); V(&empty); consume item (item); } } Explain why switching P(&empty) and P(&mutex) may create a deadlock. (Describe an example of how exactly such a deadlock occur. )
