Does Emacs allow it to implement POSIX signal handling in Lisp?

Specifically, I would like to handle SIGTERM to finish desktop-mode related things.

There's special-event-map which can be used to handle signals among other things, you can bind a key like [sigusr2] there to a function you'd like to be executed on the respective signal. I'm not so sure whether it works on anything else than SIGUSR1 and SIGUSR2 though.

edit: Here's an useful example of how one could use it:

(defun my-quit-emacs-unconditionally ()
  (interactive)
  (save-some-buffers t t)
  (kill-emacs))

(define-key special-event-map (kbd "<sigusr1>") 'my-quit-emacs-unconditionally)
