I've just scanned it (haven't had time to do detailed review yet) but it
looks pretty good to me. The only thing I notice is one or two stale
comments. For example the hashmap() function no longer has an oop as
argument but is still commented as "return the appropriate hashmap for a
given object". I also wonder about the rehashing and whether it might be
cheaper to re-hash to same slot rather than accumulating the moved
entries in the delayed_add list. Keith may have measured this already.
