The way Emacs is expected to deal with it, is via the notion of dedicated
windows. When a window is created by display-buffer, it is sometimes marked
as dedicated, so that if the buffer it displays is killed the window is
deleted (and if it's the only window in the frame, the frame is also
deleted).
I think Emacs should be a bit more aggressive about marking windows dedicated.
My locally hacked Emacs has changed it to *always* mark the window
as dedicated. The problem with that is that you can't switch-to-buffer in
a dedicated window, so I introduced the notion of "softly-dedicated" which
basically says "this window was created to display buffer FOO and has never
displayed anything else". I.e. it's a form of the `dedicated' flag which
does not prevent switch-to-buffer: instead when doing switch-to-buffer the
flag gets set back to nil to indicate that the wnidow is not dedicated
any more.
It works great in my environment, don't know about others's.
