Meanwhile, back in the real world (or at any rate in the thin
slice of the real world where super-GM chess is played): a game
S.Mamedyarov (2757) - V.Anand (2786) in the current Dortmund tournament
(first game at http://www.chessbase.com/news/2007/games/dortmund05.htm)
reached this position after 67...Bd6-c7:

White Kc4, Bg7, pawn b5; Black Kb7, Bc7

The position is clearly drawn, and after 68 b6 Kxb6 was literally
dead drawn; but the game score continues 69 Kd4 before ending 1/2-1/2.

Back in the era of the Korchnoi-Karpov matches, one game ended with
a 125-move stalemate that relieved the players of the obligation to
shake hands on a draw. But I've not read of any aversion between
Anad and Mamedyarov...
