This is a limitation we don't want, as it is too severe.  How can we
prevent loading when idle timers can run any Lisp, and an arbitrary
Lisp program can always call some autoloaded function?

And I don't understand why we'd want to have such a restriction, since
idle timers run from the main loop, thus in safe context.  It would be
a gratuitous restriction that will only draw (justified) complaints.

Can you explain why you think loading shared libraries from an Emacs
idle timer could be dangerous?  I don't think I understand that.
