   On the Amiga, any task is allowed to disable interrupts for no more

Isn't the suggested maximum time 250 *microseconds*?  250 nanoseconds
is barely enough time for a couple of memory accesses...  Think.  I
doubt Amigas have faster than 100ns RAM, and the cycle time is double
that.  Which would mean two memory accesses within your 250 ns limit.
Not very feasible, eh?

(a nanosecond is a billionth of a second...)
