But that text is stupid/defective, because you will not actually get
predictable scheduling behavior just by doing that.

Signal the condition while still holding the mutex doesn't give you any
guarantees about which thread will get the mutex next.

Suppose:

1. The signal operation wake up the next waiting thread.

2. The signaler then gives up the mutex.

3. Before that awoken next-waiting-thread gets the mutex, some
   another thread comes along and seizes the mutex.

Signaling in the mutex can blow up the critical region from "handful of
instructions" to "hundreds of instructions".

If we compare:

  mutex_lock(&stack->lock);
  node->next = stack->top;
  stack->top = node;
  mutex_unlock(&stack->lock);

  cond_signal(&stack->item_pushed);

All that is in the critical region are the mutex are the list
manipulation instructions, plus some of the mutex code itself.

If we move cond_signal before mutex_unlock, everything done by that
function, including potentially going into the kernel to wake up a
thread, is now in the mutex.

That's a lot to pay for some vague, unfulfillable promise of
"predictable scheduling behavior", on which you can base approximately
nothing.

Hoare semantics gives you something: that if there are waiting tasks
queued on a condition, the monitor is transferred to the first waiting
one. *And* (I seem to recall) when that thread leaves the monitor, the
original signaler gets it again!
