<pre>Seems to be a bug around nullability. attr argument to pthread_mutex_init is
declared _Nullable in the header on my machine but clang still complains to me
when passing NULL. Not a huge bug but it is annoying.
int pthread_mutex_init(pthread_mutex_t * __restrict,
const pthread_mutexattr_t * _Nullable __restrict);
thpool.c:37:47: warning: null passed to a callee that requires a non-null
argument [-Wnonnull]
(void) pthread_mutex_init(&tp->mutex, NULL);
