Marcel Taeumel uploaded a new version of KernelTests to project The Trunk: http://source.squeak.org/trunk/KernelTests-mt.424.mcz
==================== Summary ====================
Name: KernelTests-mt.424 Author: mt Time: 31 May 2022, 3:24:36.006029 pm UUID: 54f976c3-1296-964f-9a2a-1890202ae545 Ancestors: KernelTests-jar.423
Moves ProcessTerminateBug from Tests to KernelTests package.
Makes re-used semaphore in (Process)UnwindTest more explicit by having an AbstractProcessTest. Downside is that those 5 ClassTestCase tests will be executed too often.
Thanks to Jaromir (jar) for the pointer!
