If we were adding something for this explicit purpose, I'd prefer to
add a flag to the url function and then have TurboGears eat the
incoming "tg_random" variable so that you don't need to add another
parameter to your methods.
In some ways, it seems like doing a POST would be nicer than adding a
random hash. I did see Bob call that absolutely terrible, but adding a
random value to a URL seems unpleasant as well.
