This won't work.  If you do this, then you'll end up throwing away the code for functions that are live one the stack.  The code buffer may be reused and overwritten, and then we may may a return back into that address range expecting the old code to be there.

Right now we can only handle throwing away code if the machine stack is empty, WebCore does need to ensure that it only calls this method whilst no JavaScript execution is taking place.
