I don't want a 4GB image, but I may want a lot of normal-sized Squeak images running on a piece of "big-iron". But I guess the current VM's have some problem where the oop was defined as signed, so images cannot even *reside* above 1GB (or whatever it is).
So even if that was fixed, that would take 32-bit Squeak up to 4GB boundary, only if all 32-bits were for the oop.
... I saw this ad on the back of InfoRag earlier today. Some IBM blade, multi-Xeon-multi-core, up to 48GB high-speed RAM, "starting" at $2K. Cool, this could probably run a lot of images simultaneously, but how far could you go with 32-bit Squeak on this?

Martin - and others of course - what exactly do you want a 64bit vm for? Do you really need more than 4gb sized object memory spaces? What benefit is there to running a 64bit integer baesed vm with a 32bit oop based image? Perhaps I'm forgetting something but it doesn't seem like anything terribly useful.
