So I don't know if this is related.  But as discussed previously I also
see major random lockdown issues with tables.  For me it seems to be a
combination of company, flyspell, tables, and maybe entities.  I have
yasnippet installed but only 'cause it's required by some packages.  I
never activate it.

When looking at the profiler, I notice avl-tree--do-delete (and other
avl functions) and org-element--cache-compare taking lots of speed.  I
think I have also had this issues in mail-buffers where I use orgstruct
modes.  Again org-element--cache showed up.

Attached is a backtrace from yesterday where I had to stop Emacs with
kill -usr2.  The file I was working on has many tables with conjugations
of words and some entities.

I can get slowdowns in emacs -q but not the 100%

Cheers,
Rasmus
