Maybe I wasn't very clear. There are not only recursive fonctions. There
can be non-trivial loops in the function call graph (e.g. A calls B 
calls C calls A). And lots of funky stuff. Usually when you code
something there is no requirement about "keeping the function call 
graph clean" ;-)) So people don't bother about it...

So you may end up with a program where lots of functions won't be
optimized at all because of that.
