FreeBSD, glibc, and musl have all implemented C11 threads at this point. POSIX is looking at how to align with it. Probably time to jump on the bandwagon ourselves... Implemented in the same style as <termios.h> so we can provide this functionality even on older API levels. This does mean that this is strictly more expensive than calling pthread functions directly. Although this isn't in POSIX yet, assume that it's going to be basically the same as C11 and add the header test anyway. We should revisit this when POSIX actually adds <threads.h>.
