Ok, the question now is *should*  the joinable and interruptible features of 
a thead be disociated?
IMO they should. We can need to interrupt a thread even if we are no 
interested when the thread finish.

If should be better if the the implementation is possible, but I don't think 
that this is a big problem for the user. Most of the applications could work 
without releasing the resources that are released when a thread is detached, 
and preserv attached the thread if they want to be able to interrupt it, 
isn't it?
