Bob,
After much work (and some valuable assitance from Bob Arning) this weekend I was able to get my sim running without have Squeak become autistic (freezing up). This was accomplished by placing a Delay (1 second) between the #sendData: and #closeAndDestroy call on the socket.
BUT when I try the exact same code on 2.9a - it freezes.
Has anyone else seen this? Another engineer I work with has hung Squeak 2.9a by simply saving the image.

Have you tried forking the threads at a priority lower than the UI (i.e. use "forkAt: Processor userBackgroundPriority" instead of fork)?
This may tell you something.
A process running at or above the priority of the user interrupt handler can keep Squeak from responding to a user interrupt.
A process running below that, but at or above the priority of the UI, can keep you from being able to interact with the notifier that the interrupt handler brings up.
