 Because now there's a "download section" which just does:

        for (ndata, nmdtype) in downloading*:
            if not self._retrieveMD(nmdtype, retrieve_can_fail=True):
                self._revertOldRepoXML()
                return False

...instead of having it mixed in, and in theory it just needs to change
to something like:

        for (ndata, nmdtype) in downloading*:
            self._start_async_retrieveMD(nmdtype, retrieve_can_fail=True)
        if not self._end_async():
            self._revertOldRepoXML()
            return False

...of course that's pure guess work, and we might want to change it a
lot more so you can have multiple downloads for different repos. going
at once ... but, it's something.
