That is why I love pencil and paper. As I'm going through code I take notes. As I read doc I take notes. As I'm thinking I take notes. If I do get interrupted it's relatively easy to pick back up because I have all these notes. By the time I'm coding I'm almost always following a mostly fleshed out algorithm so it goes pretty quick.
