It occurs to me that I could get rid of the #ifdef around this by letting the
no-op stubs inlined into the header function for non-Mac in addition to
Mac-non-x86_64. I haven’t done that because the code might look a little
unseemly calling into Mach functions without obvious platform guards, but if you
like that idea, it’ll save a couple of lines.
