  // optimization: this is only called when disabling an origin and in this case
  // we don't have to remove the file from the origin

  // need to remove files from their parent directories. multiple ways to go
  // about this:
  //   a) for each file, search its parents file-list (preferably by name) and
  //      remove what is found
  //   b) gather the parent directories, go through the file list for each once
  //      and remove all files that have been removed
  //
  // the latter should be faster when there are many files in few directories.
  // since this is called only when disabling an origin that is probably
  // frequently the case
