AsyncIO: SDL_AsyncIOFromFile could be asynchronous?

[thatcosmonaut]

io_uring allows for async file opening, so it's possible that AsyncIOFromFile could take the queue object as an argument and make this operation optionally non-blocking depending on the backend. If the argument against is that this makes the behavior inconsistent across implementations, I understand, but I wanted to raise the issue just in case.

It could also make sense to use a threadpool for 'async' opens on targets that don't natively have them. Opening a file isn't guaranteed to be fast on Windows, thanks to filter drivers, virus scanners, etc.

We opted not to do it because only io_uring supported it, and we are hoping that opening is (generally) a fast operation, but also we were concerned about the added complexity to the app in making this part also async.

But let me think about it a bit.
