[O] Possible cache problems

[Suvayu Ali]

Hi,

I have been noticing a strange heisenbug.  From time to time, Org starts
eating CPU for certain specific tasks: org-end-of-line, fill-paragraph,
folding or unfolding trees, or adding/changing properties with
org-set-property.  However these happen only after I have been using Org
for a while.  

I think I also see similar CPU eating symptoms when I have buffers
editing version controlled files.  I have auto-revert-mode enabled for
files under version control, I think that is related.  I'm not entirely
sure though, I don't know how to narrow it down either.

I say it is cache related since all this magically goes away, once I go
to the top of my current tree, and call org-element-cache-reset.
However, once the symptoms start showing, it happens more frequently
despite my cache resets.

It's very hard to reproduce this though.  I see it when I have been
using the same Emacs session over several days.  I always run emacs as a
daemon, so sessions lasting a week or more is quite common.  To see the
symptoms I have to wait about half a week to a whole week, hence the
hard to reproduce comment.  However, once the symptoms show, it gets bad
rather fast.  I end up restarting when the need to reset the cache gets
too frequent.

Any thoughts?

Thanks,
