    @NicoK , thank you for giving this discussion and comments!
    
    Actually I proposed the same way of using fixed-size `LocalBufferPool` for 
managing exclusive buffers for per `RemoteInputChannel` with stephan before 
implementation. I attached the dialogue below:

    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.
