I guess it's this code?
DEFUN ("handle-save-session", Fhandle_save_session,
Shandle_save_session, 1, 1, "e",
doc: /* Handle the save_yourself event from a session manager.
A session manager can tell Emacs that the window system is shutting down
by sending Emacs a save_yourself message. Emacs executes this function when
such an event occurs. This function then executes `emacs-session-save'.
[...]
else if (kill_emacs)
{
/* We should not do user interaction here, but it is not easy to
prevent. Fix this in next version. */
Fkill_emacs (Qnil);
I started a background process that `C-x C-c' will query me about before
exiting, but calling `kill-emacs' directly will kill Emacs without
querying about those processes.
Is there a different path being taken when Emacs gets this event from
the system?
