Review comment:
Yes, it might bring this concern here.
My initial version was removing this page size parameter from constructor of
`CachedBufferBlocker`. The cached size could be got directly from
`BufferOrEvent#getSize`. But it might bring previous behavior because the real
size in buffer might be less than the configured page size. But it seems more
reasonable to get cached size from data itself.
