    lists: replace entry=list_entry(info,data) with init_list_entry(info,data,entry)
    
    And strictly enforce that the entry is uninitialized.
    
    Help prevent this ticking timebomb:
       t = connection()        // t->list_entry = ...
       insert(t->list_entry)
       i = instantiate(t)      // clone(t); i->list_entry = ...
       insert(i->list_entry)   // double insert!
    (While the hash table code was OK, this forces the clone
    function to explicitly zero the cloned lists)
    
    Need to get rid of the clone() function.
