- Any unnecessary MMU translations will slow down the OS.

- This is really, really, totally unimportant. The Amiga manuals say, by
- the way, that you should never read or write a system structure if a
- valid system call provides a way to access the structure for you. So, in
- my opinion, it's never been valid to read sysbase->ThisTask anyway!
