Review request for bookkeeper.
Summary
-------
It's been running in a loop for 30 minutes now, and doesn't seem to be hanging.
Main problem was that even after the hedwig client was closed, a subscription
request could succeed and add a channel to the channel list, though hedwig
client had already moved by the point at which it closed them.
This addresses bug BOOKKEEPER-146.
