Answer 20 in the FAQ contains:
"If threads are not used, you can declare (disable-interrupts)."
and the manual says:
"Disable timer-interrupts checks in the compiled program. Threads can
not be preempted in main- or library-units that contain this declaration."

Both are correct - and even (not interrupts-enabled) will do the same
(see manual.tex)

As I stumbled across these variations before, maybe a (drastic) simplification
would be helpful.
