@NicoK , thank you for giving this discussion and comments!
Actually I proposed the same way of using fixed-size `LocalBufferPool` for

Maybe I did not catch stephan's meaning from the above dialogue and took
the current way to implement. I also agree with the way you mentioned and the
fixed-size buffer pool for `RemoteInputChannel` can be submitted in an separate
PR.
