Can he do something with their hosting to ensure users of his site will not get this error.
As it is a browser bug, you cannot change this behaviour.
well: as the bug only occurs if prefetching links from your page fails, you could of course remove all 'href' attributes from your html-source and add them on page load using javascript. this would end in chrome not fetching up anything: no fetching => no fetching error. but this 'solution' is not practical.
