Actually it counts the number of times a buffer has been displayed in the past. Plus, if I execute (setq buffer-display-count most-positive-fixnum) and then display the buffer in a new window, I wouldn't want Emacs to crash (or to convey the existence of a supernatural power :-) simply because the counter was incremented. While we're on the topic, how about if we deprecate/obsolete buffer-display-count? As far as I can tell it's never been used in Emacs, and is not used elsewhere. It was introduced in 1997 and was superseded in 1998 by buffer-display-time, and the rare code that worries about whether a buffer has been displayed (ibuffer-mark-old-buffers, clean-buffer-list) uses the newer variable.
