  0.6 apparently uses nscd to do some name lookups, resulting in it
  holding some mmap mappings to deleted files in /var/run/nscd.
  E.g. lsof shows:

    init         1 root  DEL       REG              253,0          1850313 /var/run/nscd/dbyn3Piz
    init         1 root  DEL       REG              253,0          1850312 /var/run/nscd/dbt2e8PH

  This is a workaround - it would be better if Upstart didn't do this.
