Are you seriously suggesting that just because errors in implementation happen
(such as malformed gifs leading to bugger overflows, etc), that it's OK to have
a totally broken security model that doesn't even *try* to get it right?

"Since you *might* be able to find a hole using user-supplied data, we'll just
assumed that you *did* find one, and we'll make it easy for you and just allow
you to provide your exploit code as totally untrusted files from an untrusted source".

Hmm.. where have I heard that before? Oh yes...

Mr Prosser (who was arguing with a spokesman for the bulldozer drivers about
whether or not Arthur Dent constituted a mental health hazard, and how much
they should get paid if he did) looked around. He was surprised and slightly
alarmed to find that Arthur had company.

"Yes? Hello?" he called. "Has Mr Dent come to his senses yet?"

"Can we for the moment," called Ford, "assume that he hasn't?"

"Well?" sighed Mr Prosser.

"And can we also assume," said Ford, "that he's going to be staying here all day?"

"So?"

"So all your men are going to be standing around all day doing nothing?"

"Could be, could be ..."

"Well, if you're resigned to doing that anyway, you don't actually need
him to lie here all the time do you?"

"What?"

"You don't," said Ford patiently, "actually need him here."

Mr Prosser thought about this.

"Well no, not as such...", he said, "not exactly need..." Prosser was
worried. He thought that one of them wasn't making a lot of sense.

Ford said, "So if you would just like to take it as read that he's
actually here, then he and I could slip off down to the pub for half an
hour. How does that sound?"
