We're not talking about DOS here. This is AmigaOS, a fully preemptively multitasked OS from day one. No memory protection, but unless your code is running on bare metal like demos and games, there are other tasks running.

Top parent of this thread is talking about a package for AmigaOS being run on a bespoke emulator (as the Unusable Amiga Emulator of the 90s wasn’t really a thing that could be used for that)
