This should work with 1.8.2.

    def rbuf_fill
      if IO.select([@io], nil, nil, @read_timeout)
        @rbuf << @io.sysread(16384)
      else
        raise Timeout::TimeoutError
      end
    end

The enlarging buffer size should work well until in-kernel
TCP buffer is large enough to store data receiving between
successive rbuf_fill.

If the in-kernel buffer is not large enough, the overhead
should be reduced.  I think timeout() is the first candidate
to remove.
