This is a follow up from off line discussion with Eliot.
In order to verify the operation of the low space interrupt handling mechanism, Andreas proposed the following four tests:
* "[true] whileTrue" * "[[true] whileTrue] forkAt: Processor userSchedulingPriority + 1" * "Smalltalk createStackOverflow" * "[Smalltalk createStackOverflow] forkAt: Processor userSchedulingPriority + 1"
Each of these should be interruptable, and the mechanism should work in both Morphic and MVC. When running on a virtual memory system with swapping (e.g. Linux), the VM should be started with a specific memory size, otherwise the system will bog down in swapping without ever encountering the low space limit.
When we make a change to process scheduling, we would want to make sure that these four tests still work (which might in turn require changing the low space interrupt handling).
Background is on Mantis 0001041: [VM][ENH] LowSpaceAndInterruptHandler-dtl at http://bugs.squeak.org/view.php?id=1041, and Andreas' original discussion would be on squeak-dev somewhere in the early 2005 time frame.
