The problem is that if you say "it isn't acceptable at all", then you *VERY*
quickly end up with almost *NO* software that's "acceptable".

All software is buggy. *ALL* of it.  Learn to accept it. Making a "this is not
acceptable" declaration about something that in general is not totally
preventable is just doomed to failure.

Also, remember that programmer time is *FINITE*.  Would you have been willing
to not have the last 3 "this is indispensable" features in your favorite
software in order that the programmers track down every single possible
failure mode?  Would you give up 2? 1?

Most software projects could probably fairly easily eliminate (rough guess)
some 75-90% of the really bonehead errors via better programming methodology
and automated software testers/verifiers - but after that, it's going to be
*really* hard to get much further improvement.

There are no silver bullets....
