int main() {
    {
        pthread_t t;
        pthread_create(&t, 0, foo1, 0);
        void *r;
        pthread_join(t, &r);

I was surprised to see that pthreads worked in this case while std::thread did
not. I've also heard that boost::thread works. I'm having a hard time finding
any documentation on whether static linking and std::thread should work
together. Also see
http://stackoverflow.com/questions/7090623/c0x-thread-static-linking-problem

If it is the case that pthreads and std::thread cannot work together with
static linking, then it'd be nice to fail at some point before runtime if that
is possible.
