I don’t imagine async IO being any different on a Mill vs how things currently work. We don’t use interrupts to tell a userspace application when files are ready. The current model used by pretty much everyone is something like epoll. The application uses a single syscall to determine if many possible IO operations are possible. That syscall may optionally block, timeout, or just return immediately.
In the Mill, a syscall would be a portal. In the event you use the block/timeout option, you made a turf change the moment you portal’d into the “OS”. From there, it can switch to any OS turf thread such as one it previously preempted. However, none of this matters to a user space application which can follow the same programming model it always has.
