I am totally clueless as to C-based threads in general and pthreads in
particular. There are manual pages for pthread* things, and the library,
thus, I suppose I am.

Manual page says this.. wonder what lock->mut is, hopefully this type ;)

      int pthread_mutex_init(
         pthread_mutex_t *mutex,
         const pthread_mutexattr_t *attr
      );

Seems like non-std pthreads variant that thread_pthread.h doesn't know
about (see my other post).
