This is needed on 64-bit.

- set_thread_priority((thread_id)td, prio);

What's the exact difference? The outcome should be the same, no?
The outcome is indeed the same, but GCC treats a cast from a pointer to an
integer of smaller size as an error. So we have to cast first to an integer
of the same size and then to one of smaller size.
