<p>Return an integer identifying this object, unique for
the current execution of the program. The generic comparison
and hashing functions are based on this integer. When an object
is obtained by unmarshaling, the id is refreshed, and thus
different from the original object. As a consequence, the internal
invariants of data structures such as hash table or sets containing
objects are broken after unmarshaling the data structures.</p>
