The created Task instance keeps shared state.

    var effect = 0
    val task1 = Task { effect += 1; 3 }.memoize
    val task2 = task1 map { x => effect += 1; x + 1 }
    val task3 = Task.gather(List(task2, task2, task2))

    val result1 = task3.runAsync; s.tick()
    assertEquals(result1.value, Some(Success(List(4,4,4))))
    assertEquals(effect, 1 + 3)

    val result2 = task3.runAsync; s.tick()
    assertEquals(result2.value, Some(Success(List(4,4,4))))
    assertEquals(effect, 1 + 3 + 3)
