* pthread_msgqueue - implements message queues, more features than POSIX mqueue (no known issues, but not really tested)
* pthread_user_data - allows user to store and retreive custom data using thread handle as a key (suboptimal, used internaly, not tested)
* pthread_multi - lock multiple mutexes at once (might cause deadlocks in complex scenarios???)
