Sorry the scenario I described isn't the problem (I accidentally transposed the
time when m_rxing gets updated when reading the code). Comment #1 is still
correct though.

Below, I note NiChange as "(truncated time in hex, delta)"

>From analysing my program as it crashed (at InterferenceHelper::CalculatePer:

== m_niChanges is {(0bebc217, 6.447e-11), (0bed67f7, -6.447e-11), (11e1a317,
6.447e-11), (11e348f7, -6.447e-11)}
== m_firstPower is 0
== event corresponds is at time 11e1a317 (corresponds to 3rd item on the
vector)
== *ni is {(11e1a317, 0), (0bed67f7, -6.447e-11), (11e1a317, 6.447e-11),
(11e348f7, 0)}

This seems to suggests that at the time my simulation crashed, one packet (time
0bebc217--0bed67f7) had finished receiving, but somehow stayed in m_niChanges,
causing the incorrect ordering.

Maybe m_rxing somehow didn't get updated?
