Reply #13: The funny part is that it is vaguely possible that the realtime threads...

...that run the fuel injection and the spark *COULD* stay
alive while some lower priority threads got blocked, but
even if we put-aside the idea that braking control is probably
a pretty-high-priority thread, there's the little matter of
watchdog timers.

If the main control loop ain't executing fully, the odds are
very high that one or more watchdog timers aren't getting
reset either, and the entire system will be rebooted in the
next second or so.

But hey, as you said, among those trillions of lines of code
that are doubtless running the Prius, anything could happen,
right? ;-)
