The main thingmissing is that I would like to do some cleanup in the embedded Pythoninterpreter when Emacs exits (close open files, deal with threads/processes,etc). What would be the best way to do so?1. Can I just register an atexit handler when my module starts, or will thatinterfere with some Emacs internals?Unless you attempt to call Emacs functions in the atexit handler, that should be fine.2. Would it make sense to add support to the module API for a cleanup callbackthat is called when Emacs exits?You can already use the hook `kill-emacs-hook' as usual. That's especially useful if your cleanup needs to interact with Emacs.
