Thanks, but to do anything with this report we'd need at least to
understand what is causing the high CPU usage.  The linked Reddit post
has a profile, but only before removing those 4 lines.  Perhaps
comparing two profiles, before and after the change, while doing the
same stuff in the same build of Emacs, would give us some ideas.
