*
* To avoid infinite recursion due to cyclic structures, the hare-and-tortoise

* dimensions, vertical (indicated in the code by the variable names 'hare'
* and 'tortoise') and horizontal ('rabbit' and 'turtle'). In both
* dimensions, the hare/rabbit will take two steps when the tortoise/turtle
* takes one.
*
* The vertical dimension corresponds to recursive calls to function
* copy_tree: This happens when descending into vector elements, into cars of
* lists and into the cdr of an improper list. In this dimension, the
* tortoise follows the hare by using the processor stack: Every stack frame
* will hold an instance of struct t_trace. These instances are connected in
* a way that represents the trace of the hare, which thus can be followed by
* the tortoise. The tortoise will always point to struct t_trace instances
* relating to SCM objects that have already been copied. Thus, a cycle is
* detected if the tortoise and the hare point to the same object,
