So, I've actually studied this in real-world conditions and TCP
behaves exactly as I described in my previous email for exactly the
reasons I explained. If you think it doesn't, you don't know what
you're talking about.

Window scaling and SACK makes it possible for TCP to grow to consume
the entire whole end-to-end pipe when the pipe is at least as large as
the originating interface and -empty- of other traffic. Those
conditions are rarely found in the real world.
