// lives. Nothing deletes those copies afterwards: the share is handed to JS as a
// path and the app never learns when it is finished with it. Keeping them in one
// named directory rather than loose in cacheDir is what makes a sweep possible at
// all -- the copies carry the sender's own filenames, so there is no pattern to
// match on.
