any inadvertent reset could cause the processor to reset and cycle again!
Maybe, depends on how the code and hardware for the ignition switch is designed. If the hardware uses an on-board pulldown and only the GSE ignition switch can pull it up, it should be OK, because the ignition switch is mechanically disconnected at launch. That still leaves the "it ignited but didn't leave the rail" scenario, though.
It's definitely something that needs to be examined closely.
