Is the multi threaded implementation, being talked about for some time part of this release? Sometimes the single threaded nature of emacs causes problems while running complex setups like cider, nrepl etc.
- Guile Emacs does not seem very alive: http://git.hcoop.net/?p=bpt/emacs.git
- Remacs, a Rust port, seems to be more alive: https://github.com/remacs/remacs Does not look usable as a daily driver, though.
I sometimes wish that Xi editor adopted an elisp port as one of the scripting engines. Not very likely, though; a suitable port does not exist in the first place so far.
OTOH, being an in-place rewrite, it likely cannot afford to change some of the more important architectural decisions, very likely including the ones that prevent multithreading.
> This is also only the first step in bringing threading to Emacs Lisp. Right now there’s effectively a global interpreter lock (GIL), and threads only run one at a time cooperatively. Like with generators, the Python influence is obvious. In theory, sometime in the future this interpreter lock will be removed, making way for actual concurrency.
