<div><span style="font-family: Arial, Helvetica, sans-serif;font-size: 13px">Yes, removing the primitive form #yield will introduce one (or more) suspension points because of the (rather complex) fallback implementation. Yet, I cannot do that in a test. :-)</span></div>

The reason is the #yield primitive 167 - it doesn't reflect the change of<br>
priority as done in #valueUnpreemptively... Try to remove the primitive from<br>
#yield and then it works ok<br>
