Hi woigl,

Resource taken by a thread would remain occupied until a pthread_join() returns. i.e. resources are not freed even after calling pthread_exit(). For a detached pthread, memory reousrces are freed upon thread exit and can be recycled immediately.
You would like such an arrangement in say a threaded server where you keep a pool of min no of server threads and spawn, kill them as required. It is not necessary to know if processing completed successfully (webserver) and you would not like to join every thread, nor would it be convenient to do so.
