I'd be somewhat scared to tinker with the timeout calculations without
doing some heavy-duty research into how the modified version interacts
with a spec-compliant implementation.  Experience with TCP shows that
protocol behavior in the face of packet loss can be complex and
unpredictable and that minor changes in the protocol can lead to large
degradations in performance.
