What is "non-blocking saving"?

[voddan]

When trying to host a game I am presented with several settings, one of which is "allow non-blocking saving".

What does it mean? What does this setting changes? How does it work?
Can it be used for a single-play game?
Is it only available on Windows?

Thanks!

It's experimental feature contributed by a community member.
When autosaving, the game will fork itself and save will run in the fork in background, so it won't pause the game. It is not available on Windows at all, only on Linux and macOS.
I think there is an option to enable it in single player too.
It would be cool if you used it, but be carefull, it might cause crashes or corrupt saves, so backup your saves often.

Thanks, posila! A few questions:

- The GUI contained that option even thou I was on Windows. Is it as intended?
- Where in the GUI do I find that option for single player?
- Is there a genuine way to contribute to Factorio on the level of source code? Was it a special arrangement?

No. It's in the server settings because those are editable runtime when connected to a server which may or may not support it.
