If we want to avoid the overhead by calling `requestPartitions` on each `getNextBufferOrEvent`, we can change to trigger the request in the construction of `InputGate`. Then it will be called only once for initialization to avoid additional check each buffer level. Maybe it is not the scope of this issue. :)
