Yes, m68k does have the HALT instruction (maybe it's called differently 
but I am too laz^H^H^Hbusy to check any information source now). ARAnyM 
supports it as well as FreeMiNT thus you can have 0% host CPU load when 
running FreeMiNT under ARAnyM...

The problem is that AES in TOS (and most probably also in EmuTOS) has 
bad implementation of the mouse polling. You can never get it sleeping, 
AFAIK (that's what I heard many years ago). TOS is dead but EmuTOS could 
be fixed, perhaps, if there was any interest in this feature.
