To avoid accidentally starting Gnus a second time, I use the following
code, which requires that you have the lockfile program in your path.
After a crash, the lock file will still exist, in which case you can
steal the lock.
It's amazing how often this has saved me from having two copies of Gnus
running!
(add-hook 'gnus-before-startup-hook 'jdc-gnus-lock)
(defun jdc-gnus-lock ()
(or (equal 0 (shell-command "lockfile -r0 ~/Gnus/lock"))
(y-or-n-p "Lockfile exists. Steal lock? ")
(progn (kill-buffer "*Group*")
(error "Unable to lock ~/Gnus/lock"))))
(add-hook 'gnus-after-exiting-gnus-hook 'jdc-gnus-unlock)
(defun jdc-gnus-unlock ()
(shell-command "rm -f ~/Gnus/lock"))
