Review comment:
That makes sense, and I was debating that internally as well. However,
it would complicate the cleanup of the thread quite a bit. Since the thread
runs infrequently (every 2.5 minutes or so) I think the cost of client creation
should be pretty low, and not worth the extra complexity of storing it in a
field and worry about clean up in the various scenarios. Let me know if that
makes sense.
