May I ask if other Org operations are also slow in that problematic file
with many markers? If so, I do not think that we need to worry about
performance of `line-number-at-pos'. Rather we just wait for Emacs to
fix problems with markers. See the discussion in https://yhetil.org/emacs-devel/jwvsfntduas.fsf-monnier+emacs@gnu.org
