 I have installed mpd 0.15.15 and made just enough changes to
 /opt/local/etc/mpd.conf so that mpd runs usefully.  I can start the daemon
 with
 {{{
 sudo launchctl load -w /Library/LaunchDaemons/org.macports.mpd.plist
 }}}
 And now I can see two processes running:
 {{{
 $ ps -Aj | grep mpd | grep -v grep
 root     17635     1 17635 1edfd1c    0 Ss    ??    0:00.02
 /opt/local/bin/daemondo --label=mpd --start-cmd /opt/local/etc/Launch
 root     17637     1 17635 1edfd1c    0 S     ??    0:03.69
 /opt/local/bin/mpd --no-daemon /opt/local/etc/mpd.conf
 }}}

 Note that one of these processes is mpd itself, and the other a daemondo
 instance that is presumably responsible for mpd.  Seems reasonable.

 Now let's say I decide to stop the daemon.  My limited understanding of
 launchd leads me to believe that I am supposed to run
 {{{
 sudo launchctl unload -w /Library/LaunchDaemons/org.macports.mpd.plist
 }}}
 However, this has no visible effect: mpd keeps running and the music keeps
 playing.

 What seems to have happened is that the daemondo instance started by
 "launchctl load" was killed:
 {{{
 $ ps -Aj | grep mpd | grep -v grep
 root     17637     1 17635 1edfd1c    0 S     ??    0:20.20
 /opt/local/bin/mpd --no-daemon /opt/local/etc/mpd.conf
 }}}

 I expected both that daemondo instance and mpd to be killed.
