currently its not removing deleted items from lists. if you had an
object "A" that was installed within the lists of 20 other objects,
would I maintain a backwards lookup table of all the lists that
object is present in to find them when its marked as deleted ? i
fear that may an excessive use of resources. feel free to add an
enhancement ticket, maybe this could be an enableable option.

It appears that AttributeManager is not removing deleted items from
lists.
objectstore.py (UnitOfWork)
def _remove_deleted(self, obj):
if hasattr(obj, "_instance_key"):
del self.identity_map[obj._instance_key]
try:
del self.deleted[obj]
except KeyError:
pass
try:
del self.dirty[obj]
except KeyError:
pass
try:
del self.new[obj]
except KeyError:
pass
self.attributes.commit(obj)
self.attributes.remove(obj) <<-- THIS IS WHERE IT SHOULD
HAPPEN
attributes.py (AttributeManager)
def remove(self, obj):
"""not sure what this is."""
pass
But it doesn't do anything... Does this mean I have to throw away
all my objects that have modified collections and reload them after
every commit? I'd prefer not.
