IIRC there is no automatic way of doing this. In any case I had to roll my own with complicated locking and other weird hand off code. How is your thread terminating, are you returning from main or is it being aborted by another thread (if that is even possible)?
I've just had a look at the IOWorkLoop termination code, it is pretty complicated to get right it seems to be necessary to call thread_deallocate() followed by thread_terminate(), this is all new to me so something has changed since I last worked in this area.
