extra information for objects so we track their lifetime accurately
for those that want their DESTROY() to be predictable (this will be
a speed hit, naturally, and will therefore be optional, naturally. :)

[N.B. Don't even ask me about this now! When I have the time to

No documentation for perl function `random stuff' found
The following entry in perlfunc.pod matches /random/a:
=item rand EXPR
-
+
=item rand
-

Returns a random fractional number greater than or equal to C<0> and less
than the value of EXPR. (EXPR should be positive.) If EXPR is
omitted, the value C<1> is used. Automatically calls C<srand()> unless
C<srand()> has already been called. See also C<srand()>.

(Note: If your rand function consistently returns numbers that are too
large or too small, then your version of Perl was probably compiled
with the wrong number of RANDBITS.)
