  What's all this about MultiTasking on the ST ? You don't have a MMU (not
really and I think that's the worst failure in the ST's hardware architechture),
so you are definetely not able to run a *secure* multitasking on this machine
even if you want to - basta. All what you can call protected memory inside the 
ST is a bunch of bytes at the bottom plus the hardware registers - that's it.
  If you want to realize reasonable memory segmentation (in my experience this
is essential for TimeSharing) you MUST have a MMU.
