Re comment #3
> I second the sys_arch_sem_trywait() idea!

I don't think we need this: the select_cb struct has a member to ensure its
semaphore is only signalled once. That way, we should never block at the point
where I used the 1ms timeout since we only wait if the semaphore is signalled
and we didn't get this signal.
