New description:

 We need to handle the case where a directory is removed or moved out of
 the monitored local directory.

 ~~Specifically this case needs to be specially handled only when the sub-
 directory was moved into the drop uploader directory and a inotify watch
 for that sub-directory was added. Further investigation is needed to
 determine the proper way to remove this inotify watch.~~

 ~~So far it seems that we will respond to either the `IN_DELETE_SELF` or
 `IN_MOVE_SELF` events for each of these sub-directory inotify "watches".~~
