\subsection{toplevel}
The function top-level is the very root of the normal invocation
history stack. Control will pass to the restart function which is 
also in this file.

For some unknown reason toplevel was redefined to incorrectly
call lisp::unwind whereas it is defined (in this file) to be
interned in the boot package. We've returned toplevel to its
previous definition.
<<toplevel>>=
(defun toplevel (&rest foo) (throw '|top_level| '|restart|))
;;(defun toplevel (&rest foo) (lisp::unwind))
