Here is a problem case:

  * Start f-p-d:
    * Create a new JobQueue.
    * The JobQueue creates #{DB_PATH}.sock.
    * Create workers.
    * Workers connect to #{DB_PATH}.sock.
  * `touch catalog.json`.
  * Start new dispatcher.
    * Create a new JobQueue.
    * The JobQueue removes existing #{DB_PATH}.sock and
      creates #{DB_PATH}.sock.
    * Create workers... (async. continue...)
  * Stop old dispatcher.
    * Stop its JobQueue.
    * The JobQueue removes #{DB_PATH}.sock.
  * Created workers. (cont.)
    * Workers connect to #{DB_PATH}.sock but #{DB_PATH}.sock doesn't exist!</pre></dd>
