% Bogus argument! The case you are talking about is that where the
% programmer has a pointer to a data structure in a variable that is
% still in scope, but is not conceptually in use. You suggest that
% in the case of non-GC'ed storage the programmer could free the space
% early by calling the deallocator. Well in the GC'ed case, the
% programmer can arrange that the GC can free the data structure by
% assigning NIL to the variable.
No, I was referring to space that is still in use, but which
has marginal value and could be chucked if necessary.
