How to truly unbind global bindings?

[Alexander Shukaev]

I've just tried

(set 'global-map (make-sparse-keymap))


but issuing [C-h][b] still shows tons of mappings, especially in the
*Global Bindings* section:

Global Bindings:
> key             binding
> ---             -------
> C-@             set-mark-command
> C-a             move-beginning-of-line
> C-b             backward-char
> C-d             delete-char
> C-e             move-end-of-line
> C-f             forward-char
> C-g             keyboard-quit
> C-h             help-command
> TAB             indent-for-tab-command
> C-k             kill-line
> C-l             recenter-top-bottom
> RET             newline
> C-n             next-line
> C-o             open-line
> ...             ...


and there are so many more to come.

I would like to get rid of these completely. How can I possibly do that in
one simple function call? I would like the solution to be a total wipeout,
rather than a loop which is setting all of these mappings to `nil'. Thank
you in advance.
