note that despite the looks this is non-portable
and non-conforming implementation, it is way better
than the posted github code, but it can still clobber
errno, leak resources (and introduces cancellation
points which may or may not be conforming depending
how posix will integrate c11)

as far as i'm aware the only c11 conforming open source
implementation is the one in musl libc (and that's not
portable to other libcs either).
