Review comment:
We could simplify to make `Task` class implement
`BackPressureSampleableTask` directly, then to delete this class. Furthermore
we could remove `#isRunning` method from the interface, because task can judge
the state internally and return the boolean value via
`BackPressureSampleableTask#isBackPressured`.
