A most understandable error!

Regarding the discussion you refer to, drastically raising auto-revert-interval cannot be a practical solution in the general case, nor was it likely proposed as such. Even with the patch, polling will be used in many cases, including: filenotify failure (from running out of file descriptors, for example); deleted file; and anything matching auto-revert-notify-exclude-dir-regexp.
