Here is a screen shot of the Squeak 4.3 release image traced to 64-bit
object format, showing the image size after allocating a lot of object
memory. This is running on a box with 8GB of real memory, so the image
is about as large as can get on my computer.
The image is fully functional and can be saved to disk and reloaded.
Monticello and other tools all work, and the image can be updated from
the trunk update stream as normal. Saving the image to disk and restarting
it are slow due the file size and amount of memory used, but the image
itself works fine. Garbage collection works, and overall the performance
remains good up to the point that the operating system is forced to start
page swapping (because the image is larger than available real memory
on this box).
