Version 0.1.2 

examples: use exit() instead of pthread_exit() from main thread. OSX seems to spawn an extra thread for GLUT. As a result, we can't just call pthread_exit() because there's still one thread left after we kill all the threads we directly spawned, so the examples never stop running.

Finally, a versioned release!
