The 'halting' problem states that there is no *general* Turing Machine
that is capable of determining whether a given (Turing Machine)
program and input will terminate. It does *not* preclude one machine
examining another in *restricted* cases. For example, it would be
possible to write a turing machine to determine that the C "while
(1);" does not terminate, but that is a special case, not a general
