    @NicoK , I missed that message of `verifyAllBuffersReturned()` issue before.
    I have submitted the modifications of it. :)

> Currently the number of network buffers in {{LocalBufferPool}} for {{SingleInputGate}}
is limited by {{a * <number of channels> + b}}, where a is the number of exclusive buffers
for each channel and b is the number of floating buffers shared by all channels.
> Considering the credit-based flow control feature, we want to create a fix size buffer
pool used to manage the floating buffers for {{SingleInputGate}}. And the exclusive buffers
are assigned to {{InputChannel}} directly.
