Using lambda-forms on timers has the same problem as their usage on
hooks, they're a pain to deal with once you added them. Simple overriding
or removing them fails. Evaluating gnus-demon-add-handler several times
results in a new timer getting added every time.

#+begin_src emacs-lisp
(gnus-demon-add-handler (lambda () (message "foo")) 8 3)
;; comparison with `eq' fails with current code:
(gnus-demon-remove-handler (lambda () (message "foo")))
#+end_src

Then again, this could be easily fixed, which would certainly make
sense, no matter if the fsets are provided or not:
