- The Amiga programming documentation has always said that "pulic" memory should
- be allocated to hold messages. The reasoning behind this is that "public"
- memory would to in an area that was shared between all tasks, hence no
- copying would be needed to pass messages. Thus memory protection would have no
- performance impact on message passing. It will have an impact on task switching
- because there is more to save and restore to switch tasks.
