Releasing resources used by a pthread
To release the resources - memory for stack and householding - it is necessary to call either pthread_detach or pthread_join. The resources are not released when the pthread exits without one of these calls.
- pthread_join is called by the process or another thread.
- pthread_detach is typically called by the thread itself to release the resources when the thread terminates
