This is true. Static initialization will often generate calls to lock functions and that can be a faff to deal with. But I don't see what the point of the sched_yield() is. Using it at all is already a code smell and calling it repeatedly in a tight loop is the kind of thing kernel developers were trying to beat out of application developers decades ago because it just isn't really very helpful (and often actively harmful) with any but the dumbest of schedulers. It's certainly not very useful for avoiding thread starvation.
