Thanks.
Having read all of the references and discussions you've provided, I
see no evidence that this is an Emacs issue, as opposed to an Org
issue. I think the Org developers should take a look at this first,
and only if they provide clear evidence that the problem is due to
Emacs, should the problem come here.
