It's not a dirty buffer any more.

Go look. We've long since cleared the dirty bit.

So stop spouting garbage.

My argument is simple: the contents ARE NOT CORRECT ENOUGH to be
called "up-to-date and clean".

And I outlined the two choices:

 - mark it dirty and continue trying to write it out forever

 - invalidate it.

Anything else is crazy talk. And marking it dirty forever isn't really
an option. So..
