- Not necessarily true. Virtual memory handled via MMU is actually very
- efficient, does not affect performance significantly, and does not use lots
- of excess memory. (If you can, try using VMM on an MMU equiped Amiga, and
- see for yourself...)

- Does WinLose (popular?!!) have memory protection - I did not believe so.
-
- However, the reason that WinLose is big and slow is nothing to do with
- virtual memory or any memoy protection (if indeed it has such) - it is due
- to it being very poorly coded, and riddled with bug-fixes and patches and
- bodges etc.

- ???? I thought than memory protection was a Good Thing, not something to be
- feared. Why do you fear it so much (remember, just because people may be
- sloppy programmers, that does not mean to say that the system they use is
- bad as a result, nor that it should be avoided! Besides, if programs were
- sloppyand crashed regularly, then word would spread rapidly and those
- programs avoided).
