The API was created in the context of making the runtime thread-safe; then I
have been working on expanding and cleaning it up.  No its not based upon
any Next thing other than some ideas came from OpenStep which has thread and
mutex classes defined within it.

Here is an excerpt from the thr.h file

/* Frontend mutex functions */
objc_mutex_t objc_mutex_allocate(void);
int objc_mutex_deallocate(objc_mutex_t mutex);
int objc_mutex_lock(objc_mutex_t mutex);
int objc_mutex_unlock(objc_mutex_t mutex);
int objc_mutex_trylock(objc_mutex_t mutex);

/* Frontend condition mutex functions */
objc_condition_t objc_condition_allocate(void);
int objc_condition_deallocate(objc_condition_t condition);
int objc_condition_wait(objc_condition_t condition, objc_mutex_t mutex);
int objc_condition_signal(objc_condition_t condition);
int objc_condition_broadcast(objc_condition_t condition);

/* Frontend thread functions */
objc_thread_t objc_thread_detach(SEL selector, id object, id argument);
void objc_thread_yield(void);
int objc_thread_exit(void);
int objc_thread_set_priority(int priority);
int objc_thread_get_priority(void);
void * objc_thread_get_data(void);
int objc_thread_set_data(void *value);
objc_thread_t objc_thread_id(void);
