Hiya!  I think <mike and Steve Blasingame have described stuff at least
as well as I could, but I should mention also that there is hardware
that lets you protect portions of the address space without mapping it.
You can still fragment memory, but it's much harder for a runaway program
to trash the system or other folks' memory.  The ST and Amiga, as far as
I know, don't have the beast, so you get to live dangerously, but (1) as
<mike says, multitasking is more useful than single-tasking, and (2) there's
nothing about TOS or CP/M68K that makes programmers magically write perfect
code with no wild pointers.
