- Doing a tfork() type thing inside of minixfs is fine, since the child will
- be given access to its parent's memory just as though it owned the memory
- itself. As you point out, the child will start up in user mode, but that's
- the only real caveat (and whether you're in user mode or supervisor mode
- doesn't affect access to memory which you own, only to memory which you
- *don't* own).
-
- When (old) GEM is running it spends most of its time in supervisor mode,
- which is why the daemon isn't getting much time. The MultiTOS AES does
- an Syield() at appropriate times; someone could write an ACC to do the
- same thing under old GEM.
