Thanks for the pointers: very useful to know.  Let me try to apply
that advice with another linux emacs 20.7 business (in this one there
are about 1600 lines of mark_object references!):

Is this output more useful?

Thanks,

-----------
p.s.

BTW, I don't think that eshell is to
blame, since in some cases (although not in this one), eshell isn't
even loaded, except for

(add-to-list 'load-path "/usr/share/emacs/site-lisp/eshell")
(add-to-list 'load-path "/usr/share/emacs/site-lisp/pcomplete")
(load "eshell-auto")

and eshell-auto consists mostly just of autoloads.
