Both Pharo and Squeak seem to do that. This looks a bit odd and I wonder if anybody
remembers if there have been issues with the wakeup in the past?

kind regards and I wish all of you a happy holiday season


PS: With the Cogit/StackInterpreter (not spur) I seem to end up having the wrong
receiver in top of stack. I don't know if that is a Pharo/Opal issue or something with
the VM itself.
