When running k2mosaic mosaic with multiprocessing enabled, I get, at some random point in time, the following error:

FileNotFoundError: [Errno 2] No such file or directory: '/home/gb/.astropy/cache/download/py3/urlmap.dir'

I wonder if it's because astropy's download_file function is not thread-safe.
