Alright, cool. Thought for a minute the crash may have exploded the hard drive or something, but I guess since the Xbox itself didn't freeze it's not really a problem, and I can just use the "reboot" function to clear the ram later on before I launch Destiny, just to be safe. Strange that you'd have to do that, but whatever. Guess it's just one of the perils of having what's basically a tiny computer in your living room.
