Recipe: emacs -Q M-x desktop-save-mode C-h v kill-emacs-hook M-x kill-emacs Expected behavior: emacs is killed. Actual behavior: asked "Save desktop? (y or n)" The same behavior occurs if I send emacs SIGTERM. In particular, this behavior occurs if an `emacs --daemon' instance with no running clients is sent SIGTERM, which results in it... not quitting. Sending SIGTERM twice kills it, but this is very idiosyncratic behavior.
