I don't know anything about Windows, but that seems like the right sort of approach; also is there such a thing as a network block layer you could temporarily break by disconnecting it? On other OSes there are fault-injecting drivers you can use to simulate IO errors. Maybe something like that exists? In fairness to the team handling their Twitter account, I recognise that it is completely the wrong forum to ask complicated kernel questions, it's impossible to get through the front-line silly question filter. (Try reporting a kernel bug to Apple; it seems to be impossible, they're all set up to receive bug reports about consumer UX stuff etc, there isn't even a drop-down option for "kernel", and reports complete with reproducers filed under "other" just linger unanswered. These mega-corps aren't like open source projects.)
