I understood and experienced that the main thread blocks. But how can it join other threads, if it is blocked? That doesn't seem consistent to me.

[Nat] Usually one wouldn't create a thread and then immediately join() it. The net effect of that would seem to be an expensive function call. Usually if you want a new thread to run in parallel with the thread that created it, you let both threads run for a while before one thread attempts to join() the other.
