<p>Hi Levente,</p>
<p><br>
</p>
<p>thanks a lot for your answer, this was exactly what I was searching for! :-)</p>
<p><br>
</p>
<p>Regarding the suspension points, do we have any good documentation on them, preferably on the image side? I am still having problems understanding when the VM would suspend the active process - does this only apply if a process with a higher process gets
scheduled by the VM? Wouldn't it be an option to express this intent explicitly, similar to #<span>valueUnpreemptively?</span></p>
<p><br>
</p>
<p>Best,</p>
<p>Christoph</p>

Indeed. Sometimes the information is expessed in a comment, like how<br>
DelayWaitTimeout >> #wait or MCHttpRepository >> #webClientDo: does.<br>
But there's code that just relies on the behavior without mentioning it. <br>
E.g. Semaphore >> #waitIfLocked: or Semaphore >> #critical:ifLocked:.<br>
Perhaps the best way would be to introduce a pragma to mark such methods.<br>
