Part 1: The signal operation is the last operation of both functions in the bounded buffer monitor. Consequently, there is no need for the signaling process to block on the urgent queue since, upon reentry, the process would just exit the function.

Simplify the implementation of the bounded buffer monitor by eliminating the urgent queue.

Part 2: A classical synchronization problem is an analogy of a single-lane tunnel, also known as the single-lane east-west bridge. To avoid a deadlock, cars must be prevented from entering the tunnel at both ends simultaneously. Once a car enters, other cars from the same direction may follow immediately.

Ignoring the problem of starvation, solve the problem using semaphores.
Hint: The tunnel problem is a variation of the readers/writers problem where multiple readers or multiple writers are allowed to enter the critical region,

Part 3: Write a monitor for the tunnel problem that guarantees that no direction of travel can be blocked indefinitely and thus prevents starvation.
