    I'd be happy to, next time I'm trying to recover a session (I tidied
    away the previous recovery file once I'd hand-loaded the buffers it
    told me I'd had open).

You can use the shell's `kill' command to kill a session at any time.
Just make sure you have saved all the files you really care about.
Visit some unimportant files and make changes that you don't really
want to save, then kill Emacs from outside with `kill', then try
recover-session.

                            Is this stepping through elisp execution in
    the elisp debugger ?  How do I do that ?

It is in the Emacs Lisp manual.
