Nice stuff. I'll try to integrate it soon.

What I might also do is extend the list policy so that insert
and erase operations take an allocation traits object. That way
I can use the per-handler custom allocation for list nodes in
the hash maps where entries are associated with operations, and
your pooled hash map for everything else.
