That's why I said I was clutching at straws. However, circuits sometimes do
very funny things when under higher than normal power drain while at low
power levels (and this was also in a transitory environment, i.e. a reset).
Rapid changes in voltage can do odd things to digital circuitry. In this
case it would've had to somehow trigger the deep reset. I have no idea how
isolated the logic for that is from the logic for a normal reset and if a
voltage transient could flip you over from one to the other. Given the
robust nature of the Newt, one would like to think it was at least *that*
fault tolerant, but it was built by human beings...
