But isn't this just the same as any other program that contains a
blackhole fault? i.e. the program is logically incorrect. What is
more, the runtime system will probably tell you "Blackhole detected!"
or "<<loop>>" or something, which is helpful.
So I don't see why this sort of program would become particularly
more common than it currently is, if the runFinalizers() procedure
is added to the FFI spec.
