I started emacs with "emacs --daemon". I stopped it with the
"kill-emacs" command. Emacs stopped, but the desktop lock file
remained. Following is the my console (not showing the
"emacs --daemon" command).

I'm pretty sure that older emacsen deleted the lock file
when the daemon was stopped, so this looks like a
regression. If it makes a difference, there was an
existing .emacs.desktop file when I started the daemon.
