[REQUEST] Continuous session autosave

[betaprior]

Describe the feature
Currently, Doom does not gracefully recover from unclean shutdowns. After a system crash, I discovered that persp.el workspace autosaves, as well as recentf file were both last written to over a week ago. This is disappointing, as just about every other piece of modern tooling provides an option or a plugin to do regular checkpoint saves. It's quite unfortunate that I can instantly restore my browser tabs and my tmux windows after a crash, but not my emacs state.

I tried adding this piece of code to my config:

(run-at-time (current-time) 300 'recentf-save-list)

But this only resulted in recentf being completely cleared after I restarted the server, even after a clean shutdown. So there's probably something else that doom-emacs does that hooks into recentf that makes it non-obvious what to do in order to autosave.

But this only resulted in recentf being completely cleared after I restarted the server...

Yeah, I noticed that too. Life is ironic like that. Here was my workaround:

(after! recentf
  (recentf-load-list)
  (run-at-time nil (* 120 60) #'recentf-save-list)) ; every 120 mins

I kind of wish the "wrote recentf" message didn't appear in the minibuffer, but other than that it works well enough.

@betaprior What happens when two different emacs instances are open? Does (run-at-time nil (* 120 60) #'recentf-save-list)) make them overwrite each other?

I wrote this Doom Emacs module that provides rotating backup-ed sessions every hours and handles multiple simultaneous Doom Emacs instances with a lock file.
