More concrete example:

1. Send packet 1, 2, 3, 4

2. Ack 1,2,4. 
3 is lost 
largest_sent = 4
largest_acked = 4 

3. loss_time is set now to send_time(3) + 5/4 rtt

4. Send 5
largest_sent = 5
largest_acked = 4 

5. timer for 3 fires
DetectLostPackets(4) is invoked

since largest_acked != largest_sent

delay_until_lost = infinite

so packet 3 is not lost in this round and needs to go through another round
