The following are examples of notifications that were shown twice in Adium: * http://jonasl.jaiku.com/presence/4ebf00e0b2b240569db2c7c981454f88 * http://matpe.jaiku.com/presence/0d519b1ef9bc41e5a311ced473520663#c- 65f505eb5ac0469094f25af2194ddd94 * http://tomasw.jaiku.com/presence/55d3a805b9ed4244a2020f2146ba551b#c- 7f55131c163a476f8c6cc88a8a862415 For each pair, both entries were posted within a second of each other.

The 2 notifications that I see in Adium seem to be formatted differently. I suspect that one is the html format and one is the plain text version.

Some research has yielded that a property of app engine's datastore causes quick updates to the same entity sometimes to take more time to propagate allowing a quick refetch of it to sometimes get the old data, the approaches to fixing this are either: 1. change the architecture such that tasks always delete and write a new task with a different key name 2. add an additional lock in memcache to track progress on tasks

This suggests that we load the same property from the datastore multiple times. We could also avoid reloading multiple times. If this were possible then it would be a simpler solution
