    # [xx] When during downloading is it 'safe' to abort?  Only unsafe
    # time is *during* an unzip -- we don't want to leave a
    # partially-unzipped corpus in place because we wouldn't notice
    # it.  But if we had the exact total size of the unzipped corpus,
    # then that would be fine.  Then we could abort anytime we want!
    # So this is really what we should do.  That way the threaded
    # downloader in the gui can just kill the download thread anytime
    # it wants.
