Hmm, good question. Looks like we've implemented the relaxed_* variants by aliasing them to the normal version since the dawn of time. There's a comment in io.h saying something about us not having the expected semantics for the relaxed variants, but I don't see what the issue is...

Yeah that's pretty gross.
