I have a small optimization:

            if (
                # start with inexpensive checks
                roles is not _noroles
                or name is None
                or value is None
                or container is None
                # now the expensive ones
                or hasattr(value,'__roles__')
                or not hasattr(aq_base(container), name + '__roles__')
                ):

If we replace "hasattr(value,'__roles__')" above by
"hasattr(aq_base(value),'__roles__')", then the (discarded) roles computation
becomes a bit cheaper.
