  55  * Directories are relative so they are based off local_path.
  56  * Notice that we continue to use the underscore convention even though
  57  * buckets are inside the AUTO_DIR_FS and do not conflict. Visual help:
  58  * you can see what to delete right away.
  59  *
  60  * We want our own Mongo instance for autostart. Mongo does not have
  61  * a feature "listen on port 0 and tell us what you got" (like Hail),
  62  * so we define a port and hope it's not in use...
