Marcel Taeumel uploaded a new version of Kernel to project The Trunk:
http://source.squeak.org/trunk/Kernel-mt.1009.mcz

==================== Summary ====================

Name: Kernel-mt.1009
Author: mt
Time: 2 April 2016, 12:23:20.21041 pm
UUID: bd1b45d5-cb4d-41b0-890b-c8f70de70b1c
Ancestors: Kernel-ul.1008

Recent CogVMs do not yield preempted processes. Fixes the behavior where "[ [] repeat] fork" could not be interrupted anymore via CMD+. and hence locked the image.
