I don't really like this. It penalises platforms like Intel's Tiger box that have contiguous memory. I'd really like to see VIRTUAL_MEM_MAP go away and the DISCONTIGMEM code be usable for both zx1/sx1000 and sn2. -- "Next the statesmen will invent cheap lies, putting the blame upon the nation that is attacked, and every man will be glad of those conscience-soothing falsities, and will diligently study them, and refuse to examine any refutations of them; and thus he will by and by convince himself that the war is just, and will thank God for the better sleep he enjoys after this process of grotesque self-deception." -- Mark Twain
