It still interferes with any user customization, (e.g. the
my-ielm-mode-hook in the file attached upthread)

(let (kill-buffer-hook (executing-kbd-macro 'kludge) buffer-file-name 
kill-buffer-query-functions) (kill-buffer "*ielm*")) -- used as outlined in the 
quoted portion below, to opt out of saving history for "this" particular ielm 
session.

I agree it is outside the design-scope of the current implementation,
but it does still hurt, -- Regards, Madhu
