Thanks for the update.

Sounds reasonable.

Well, there are perhaps two differences between Squeak and Cuis that are 
relevant: One is that the code that checks for changes in the Screen 
size, and recreates Display as needed is completely different, possibly 
resulting in a different call pattern to platform primitives and Display 
memory allocation. The other difference is that by default, VectorCanvas 
uses additional buffers of Display extent, so memory stress is larger. 
Cuis can still go back to BitBltCanvas, but you lose the VectorGraphics 
stuff, going back to a more basic UI api.
