[BUG] org-element-cache bug: org-persist-read persists seemingly forever

[Samuel Wales]

this reproduces most or all of the time.  idk if it is ueful to
anybody, but i thought i would post it in case it is instantly
recognizable.

emacs 25.  latest 9.5 org main.

Debugger entered--Lisp error: (quit)
  read(#<buffer  *temp*>)
  org-persist-read(org-element--cache #<buffer other--a.org>)
  org-mode()
  set-auto-mode-0(org-mode nil)

Thanks for reporting!
Apparently read is being very slow when reading cache for other--a.org
May I know what is the size of other--a.org?

Next time you see the slowness, could you look into
`org-persist-directory'/index file, find the other--a.org and look at
the value of :persist-file property in the same list? Then, can you
check that persist file size?

Best,
Ihor

20051 135025 938122 other--a.org

this is a smallish to middling file for me.  my largest is 4x larger.
i haven't gotten new org to work yet so i haven't revisited this yet.

This is odd. It only takes 2 sec to write caches for my largest 15Mb
file. Though I have SSD.

I just pushed a change to org-persist. Now, Org will show a message with
some info about read/write duration when the duration is >0.5 sec. If
you see messages from org-persist can you report them?

Best,
Ihor
