	key2 := "key2"

	km := kmutex.New()

	go func() {
		fmt.Println("--- Task 1.1 Start ---")
		km.Lock(key1)

		time.Sleep(1 * time.Second)

		km.Unlock(key1)

		fmt.Println("--- Task 1.1 Finished ---")
	}()

	go func() {
		fmt.Println("--- Task 1.2 Start ---")
		km.Lock(key1)

		time.Sleep(2 * time.Second)

		km.Unlock(key1)

		fmt.Println("--- Task 1.2 Finished ---")
	}()

	go func() {
		fmt.Println("--- Task 2.1 Start ---")
		km.Lock(key2)

		time.Sleep(1 * time.Second)

		km.Unlock(key2)

		fmt.Println("--- Task 2.1 Finished ---")
	}()

	go func() {
		fmt.Println("--- Task 2.2 Start ---")
		km.Lock(key2)

		time.Sleep(2 * time.Second)

		km.Unlock(key2)

		fmt.Println("--- Task 2.2 Finished ---")
	}()

	time.Sleep(10 * time.Second)
