Faster message passing, faster context switches (no need to copy memory and translate addresses (MOVES instruction)), but best of all, the ability of programs to access its other address space directly. I for one think its really neat to have hacks such as Vscreen, Dmouse, Snip-It and others which would be rather impossible to implement if the single addressing space was not used. > > I stand by the model of the ideal real-time message-based operating system. > > Exec is pretty good, but I wouldn't say ideal. I was saying that ideal is what I propose for virtual memory and memory protection. Indeed, Exec is not ideal as it stands now, but it will be after I upgrade it. :-) Valentin _________________________________________________________________________ "An operating system without Name: Valentin Pepelea virtual memory is an operating Phonet: (613) 231-7476 (New!) system without virtue."
