 * Please note this is an atypical TestRunner:
 * - no Assertion can be done
 * - it cannot be executed automatically

 * it exists to make easier tests while changing low level stuff (it would be better and faster to use the Demo kernel but
 * sometimes it is a problem to make it see modifications done at low level)
 *
 * Remember to comment this test again on TestKernelSets.cs when you are ready to merge your modifications!
