I actually do this sometimes when it's near the end of the day and I know the problem at hand might cost a few hours. I'll write a comment but not in a code comment, exactly like the article suggests. Funny enough, it never had to serve this exact purpose and had I written the comment so that it wouldn't prevent a build, I would've still continued where I left off. I think (but am not sure) the fact that I wrote it down at the end of the day makes sure I don't forget.
