I sincerely hope that the virtual memory in 7.0 IS NOT one large space shared by all processes--just like my present Mac but with more memory. That is the one thing I HATE HATE HATE about the Mac (which I am otherwise crazy about :-)). One errant program crashes the entire system. To come home from UNIX (with harmles core dumps) to the Mac (with heart-wrenching system bombs) can be traumatic. And even worse: you cannot tell which program caused the crash! It might have been caused by a program you ran a half hour ago (or at least that is my experience). I would rather have the system and applications protected from each other without any virtual memory than have TONS of virtual space with crashes being that much more spectacular.

If you have the hardware resources, have you considered A/UX? I develop all my Mac applications under A/UX, including XCMDs. If I want an actual Mac binary, I transfer the source over to LSC. A/UX is also more stringent in 32-bit clean, no-no memory accesses and priviliged instructions etc. -- helps keep your app inline for 7.0 and later releases. +-----------------------------------------------------------------------------+ |Philip K.
