Maybe this is intentional or unavoidable, but I noticed that it's possible to start the same bot more than once.

For example:

1. I restart Relax, so that it's running all my bots (exactly once each).
2. I manually start a particular bot n times by calling Relax::Bot.start!(uid, token) from irb.
3. I send a message to that bot.
4. Sending message_new for this user and channel and sending event back to client each appear n + 1 times in the logs, followed immediately by ignoring, not sending event back to client n times.

It's not a problem, because it ignores all but 1 of the copies of the message, and puts only 1 event into redis. But I was surprised that it was possible to start the same bot more than once.
