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.

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
