Oh yes, you write a program that looks like a device driver and claim that
it's just another program running in the background. Gack.

You can not take a random Macintosh program and stick it in th background.
It's tied to GetNextEvent. When you can run a compile concurrently with Photon
Paint then you can make the claim that the Mac supports background processing.

I've been able to do that on the Amiga for years. Even before I got my RAM
expanded, though I couldn't actually compile and run Deluxe Paint together
in 512K. Now with plenty of RAM I can compile a program while using Photon
or Deluxe Paint to work on the imagery... without really slowing the compile
down, since the program isn't busy-waiting on GetNextEvent. It's limited by
my speed.

Even with 512K Deluxe Paint got along fine with all manner of programs. Plain,
ordinary, programs that don't require learning a whole new paradigm.

Because on the Amiga, as on UNIX, the operating system handles time-slicing.
Your program can completely ignore the user interface, sit on the CPU as long
as it wants, and the system will happily chug along.

If you guys had written a decent conventional O/S for the Mac and stuck the
user interface on top of it I'd be using it now instead.
