I'm not sure about the OS that ran on those old Ataris, but I know that
on the Amiga OS, which had full preemptive multitasking, any task could
shut down that multitasking and grab the CPU all to itself with a single
call to the "Forbid" system call. Calling "Permit" handed the CPU back
to the scheduler.

I'm sure all hell would break loose today if modern OSs had something
like that, but it would certainly make some tasks -- like low-latency
MIDI processing -- a lot easier to implement :)

Thanks
Leigh
