--- Comment #3 from Richard Scheffenegger <srichard at netapp.com> ---
Immediately clamping cwnd down to rwnd is not a viable solution, as TCP flow
control might be in actual use by the client (dynamically adjusting rwnd within
<10 RTTs, depending on processing state of the received data). Thus a slow
decay as mentioned in  7661 is probably the correct course....
