No, I don't think that's what's happening.
The in-flight one, which is the most egregious example, shows the queue
gradually draining at the end of the flight, when all the passengers have
been told to turn their lap warmers and fondleslabs off.
I personally have seen 45 seconds buffering delays with continuous delivery
at half a megabit or so, resulting from a market segmentation shaper in a
3G network using a big, drop tail queue. In fact, I could probably
reproduce that effect using the hardware in my hands right now.
The FireBrick, a custom firmware router made by A&A to go with their
services, is reportedly capable of rebooting without losing a packet. But
it does so by completing the reboot extremely quickly - a fraction of a
second. (It doesn't run Linux.)
