Ah, that's worrisome.  Do I understand you correctly that to work with
ra_serf in skelta mode, callers need to make their apply_textdelta
callback thread-safe?

Or do you just mean that the traversal order is based on the order in
which results are received?  That would be fine, as long as after each
apply_textdelta call, close_file is called before the next
apply_textdelta.
