I'll add in code to log errors. I'm not sure where it would make sense
to report the errors. Generally, for errors during a client operation,
we would like to report them to the client, but the client might have
already disconnected. I guess in that case it's OK if they just go to
the log? The client could warn on a timeout while waiting for index
-helper and direct people to the log.
