> The LocalBufferPool will be unavailable when the maxBuffersPerChannel is reached for this channel or availableMemorySegments.isEmpty.
> If we request a memory segment from LocalBufferPool and the maxBuffersPerChannel is reached for this channel, we just ignore that and continue to allocate buffer while availableMemorySegments isn't empty in LocalBufferPool.
