------------------------------------------+---------------------------------
 After choosing "Logout" sugar-datastore keeps running, so when the next
 Sugar session starts up (which is immediately afterwards on DebXO) two
 sugar-datastore instances are running, both trying to write the Xapian
 index and both failing. We should make sure sugar-datastore has stopped
 (wait for DBus signal Stopped) before exiting sugar-session.

 On unclean shutdowns (e.g. zapping the X server with Alt+Ctrl+BS) the
 situation is similar, though it's less clear how to handle that case (as
 the old instance cannot be reached via DBus from the new session - maybe
 use a PID file?).
