GNU Emacs 29.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version 2.24.33, cairo version 1.16.0) of 2022-07-26

Practically every time I start up Emacs, I get this pointless warning and a question if I really want to use the desktop file anyway. If there were actually another Emacs running, this warning would be fine, even useful. However, in 95% of cases here it happens because computer was shut down, Emacs crashed etc. In fact, I have just now verified that even if I cleanly `M-x kill-emacs RET' my Emacs and then start a new one, the new still thinks that the old, killed Emacs might still be using the desktop file somehow (i.e. PID is that of the previous Emacs process).

The code in `desktop.el' should really check if the process with that PID still exists before claiming that it might be using the desktop file somehow.
