Ah... a case of model versus implementation.  For Most algol like languages
the invocation of procedures/functions is nested, so a model of the invocation
sequence history is a stack of contexts.  If a machine has hardware that looks
like a stack, the mapping from the concept to the hardware is simple and
natural.  Otherwise, the mapping is not so simple and natural.  Irrespective
of the implementation, the underlying model is still a stack.
