`ielm` seems to be adding a dummy process to its buffer using either
`cat` or `hexl` binary.
--8<---------------cut here---------------start------------->8---
;; A dummy process to keep comint happy. It will never get any input
(unless (comint-check-proc (current-buffer))
;; Was cat, but on non-Unix platforms that might not exist, so
;; use hexl instead, which is part of the Emacs distribution.
(condition-case nil
(start-process "ielm" (current-buffer) "hexl")
(file-error (start-process "ielm" (current-buffer) "cat")))
(set-process-query-on-exit-flag (ielm-process) nil)
(goto-char (point-max))
