 # Notes:
-# 
+#
 # Persistent classes are non-ghostable.  This has some interesting
 # ramifications:
-# 
+#
 # - When an object is invalidated, it must reload it's state
-# 
+#
 # - When an object is loaded from the database, it's state must be
 #   loaded.  Unfortunately, there isn't a clear signal when an object is
 #   loaded from the database.  This should probably be fixed.
-# 
+#
 #   In the mean time, we need to infer.  This should be viewed as a
 #   short term hack.
-# 
+#
 #   Here's the strategy we'll use:
-# 
+#
 #   - We'll have a need to be loaded flag that we'll set in
 #     __new__, through an extra argument.
-# 
+#
 #   - When setting _p_oid and _p_jar, if both are set and we need to be
 #     loaded, then we'll load out state.
-# 
+#
 #   - We'll use _p_changed is None to indicate that we're in this state.
-#
