I have a question for SICStus Prolog expert.

It is related to freeze predicate.  The question is how to get *all*
blocked goals so far? 

What I need is similar to call_residue/2 but return all blocked goals
from top level to current point.  call_residue(+Goal, ?Vars) only
returns blocked subgoal(s) of the execution of Goal, not *all* of the
blocked goals to that point.

I tried to use setof/2 with frozen/2 but they always return TRUE instead.
