Actually, it can only detect when it is way too big.  In the case when it 
almost fits, i.e. off by one line or so, it must guess.

The main reason is that Firefox calculates its window height before mapping 
the window.  Emacs on the other hand first maps with tool bar off and later 
adds that (in lisp) and the menu bar.  Font changes in lisp are also applied 
after the window is shown.
