desktopcouch restart fails a lot on my n900

[Thomas Vander Stichele]

example:

sbox-FREMANTLE_X86: ~] > run-standalone.sh dbus-send --session --dest=org.desktopcouch.CouchDB --print-reply --type=method_call / org.desktopcouch.CouchDB.getPort
method return sender=:1.71 -> dest=:1.72 reply_serial=2
   int32 54490
[sbox-FREMANTLE_X86: ~] > run-standalone.sh dbus-send --session --dest=org.desktopcouch.CouchDB --print-reply --type=method_call / org.desktopcouch.CouchDB.getPort
method return sender=:1.71 -> dest=:1.73 reply_serial=2
   int32 54490
[sbox-FREMANTLE_X86: ~] > python2.5 /usr/lib/desktopcouch/desktopcouch-stop Apache CouchDB has been killed.
[sbox-FREMANTLE_X86: ~] > run-standalone.sh dbus-send --session --dest=org.desktopcouch.CouchDB --print-reply --type=method_call / org.desktopcouch.CouchDB.getPort

I'm not sure why I'm getting eaddrinuse. I don't know what config desktopcouchis starting couchdb with; is it reusing the same port number from a previous run ? If so, that might explain, and is probably a mistake - it should be using a new, available port; ports can take a while to close.

As reported in a separate bug, it's pretty terrible that desktopcouch cannot properly wait for couchdb to either start up correctly or not. This is going to cause you guys no end of heisenbugs.
