> +window whenever the timer expires.  In practice, this is similar to TCP with
+F-RTO, but it does allow more packets to be sent when the congestion window was
+not fully utilized prior to the probe timeout expiring. Though this is slightly
+more aggressive than TCP RTO, it's less aggressive than if the connection was
+not application limited.
