I am. I was thinking to test cases of particular interest, during make
check.

It is not an easy fix. I was assuming that receiving a packet is enough
as an indicator that the previously sent flight was received. Clearly
this is not enough if a whole flight is lost and a retransmission
occurs. I'm in the process of making this check more clever to cover
this case.
