1) Disable() turns off interrupts. Forbid() disables task switching.
2) Throw up a 1-bitplane black screen. Or, disable video DMA with
   the OFF_DISPLAY (sp?) macro.
3) Sure, you can disable anything you want. I think you'll understand more
   if you read:
     a) The Amiga Hardware Reference Manual
     b) The Amiga Rom Kernel Manual: Exec
     c) The Guru's Guide to the Amiga : Interrupts, by Carl Sassenrath
4) Possibly, but I'd warn against it. Could break in the future.
