Description
To ensure fast failover config polling would work correctly, I wrote a small Python script. I noted that the config poll wasn't happening as expected. Turning up the log level, I see that there is another param that needs to be set.
My script has
cluster = Cluster('couchbase://localhost?config_poll_interval=2.5')

I'd suggest we need to coerce the other setting down if this one is adjusted. At the very least, it needs to be documented better.
