- Charles, have you ever taken a class in computer science? The first one
- I took, a C programming course, introduced arrays during the second week.
- Consider this program:
-
- int array[4];
-
- main(){
- int i = 0;
- while(1)
- array[i++] = rand();
- }
-
- This program uses no pointers or dynamic allocation. It would kill AmigaOS,
- but an OS with memory protection would kill *it*.
-
- What are you trying to say, anyway, that memory protection is useless? Shall
- we revive *that* thread?
