I agree - if your server can take it let it do its thang, unless it is chewing up all that bandwidth on just a handful of pages - if the googlebot is getting caught in an artificial loop on your site it will eat bandwidth like nobodies business and there is even a chance (albeit very slim) that the precautions put in place to stop the very old scam of looping pages together to increase PR will kick in, penalising your site or worse.
