Issue #130 resolved

need an ordered, weak referenced Set object

Michael Bayer

right now we have HashSet that uses the underlying OrderedDict for an ordered set. the unit of work would benefit from a version of this that stores its values weakly. this would involve either changing OrderedDict or adding a WeakOrderedDict object. using it in the unit-of-work would assist in automatically removing memory-removed objects from the unit of work, preventing the insertion of "ghost" objects.
