Adding conservative exponential phase after the aggressive exponential
phase was the original intention, but the conservative exponential
approach (e.g. n' = n * 11 / 10) is slower than the existing linear
(n' = n + 1024) approach when n < 10240, so I added that intermediate
phase to avoid a regression in the packet size growth.
