Bug Description

As can be seen from https://pastebin.canonical.com/55693/, it takes about 15 minutes for the XML-RPC queue runner to complete all the sync it needs for Launchpad.

This means that we can process new subscribtions and mailing only about 4 times per hour. And this is probably not going to get better as the number of mailing lists and subscribers is going to grow.

Changed in launchpad:

The combination of enabling batching and optimising the DB calls made by the XML-RPC requests has brought the cycle time down to 4 minutes -- 15 times an hour.
