interesting.  that would be great to speed it up.  [i just meant that
the file list used to be correct.]

but it is slow these days.  for me, (benchmark-run 1 (length
(org-refile-get-targets))) is 8s for 5886 targets.

i presume you mean something like that up heading is unnecessary
because you can keep a running olpath as you search.
