import_all_app_install_data leaves files in /tmp

Hi Lamont. Can you be more specific? It will create apt caches, but re-use them on every run if they already exist. I'm assuming we don't want to blow away the complete cache for each series each time it runs, but perhaps there's files within that can be blown away? (if it is related to the apt cache, it could just be a matter of running apt-get clean for the specific cache (-o=? in the --help))

Hi Lamont - when you get a chance, can you let me know if the tmp files are apt-caches (which we may want to keep - assuming there's only one for each series/arch), or something else? A sample of the contents will help identify which code isn't cleaning up after itself.
