Ah, so, this raises an interesting question: what do people use yes for? One answer (a bad answer) is "generating artificial load". This makes the I/O strategy oddly relevant -- different strategies result in different numbers of syscalls and (potentially) kernel lock acquisitions. Couple this with someone trying to benchmark something's behavior with an antagonist load, and the story gets downright painful to contemplate in terms of confusing results. Source: in my younger years, I did this. In more recent years, I've seen other engineers do it.
