I'd wager that there's 138k lines of code for which Linus could drop into the code and figure out what's going on in a couple of minutes, in the same way as this; at least he could in the past. I've watched realtime conversations on IRC and in other realtime environments where he exhibits exactly this kind of comprehension of huge swaths of Linux. Linux just happens to be vastly larger than this now. Not to dismiss this guy's impressive grasp of his chosen language and the things he's built in it; watching him using so many tools that seem to be of his own devising is impressive as hell. Downright intimidating, in fact. My lifetime software output becomes practically zero in comparison.
