when an nsqd first sees a topic queries nsqlookupd to identify any channels that the cluster might know about in order to proactively create them (in the case where there is more than one channel this prevents data loss due to timing of consumers subscribing). in nsqio#176 a regression was introduced that prevent the topic's messagePump state from being updated in the code path described above. This meant that an nsqd that identified channels during creation of a topic would not begin writing those messages into its channels.
