As recently discovered by a user, the current RTT measurement is delayed by almost one RTT and coupled with underlying packet handling mechanism.

The coupling of data ACK and RTT measurement can break the accuracy of RTT measurement very nastily (no measurement will come back for a long period of time because of delayed accumulative ACK) in extremely deep buffer(200 times of BDP) + small bandwidth environment (e.g. hotel wifi).

This is a software implementation deficit and should be fixed.
