clang has some pretty get sanitizers now (even if you prefer gcc most
of the time for some bizarre reason, it's worth using the sanitizers,
especially the threading one if your platform supports them. I'm
pretty sure BSD does if not Linux.

Most of the formerly useful Usenet groups have become practically
worthless, including the threads specific one which used to be quite
active with real discussions about threading.

I can't think of a single reason why anyone would prefer to use that
ridiculous stuff in C11 for threading. pthreads is already there and
well vetted.
