Would love to see the considerations that went into that design!

Does it try to keep state across such a reboot? Is the first course of action to try to deduce whether it's about to crash? Is every sensor reading done multiple times to reduce risk of reading wrong (typically, such sensors are basic and doesn't employ error checks or such)? Does it try to understand why the OS crashed and do any graceful degradation, eg "fine, don't use that sensor then"?
