the assert statement is a pre-condition of maximum_stacksize().
is_stack_unbound() returns true if the stack is not limited.
calling maximum_stacksize() is only allowed if is_stack_unbound() 
returns false.
this is a issue required by posix getrlimit() - the max stacksize to a 
certain value or unlimited (== RLIM_INFINITY).
