If configured with a single host (a load balancer), the client will pause for 1s everytime it loses this connection. The same thing happens when configured with a list of hosts and the client reaches the end of the list...it pauses for 1s before going back to the top.
I don't think it's appropriate to ask for the client to constantly spin on trying to make a connection if in fact none can be made.
Another solution to this would be to have the client be aware of ALL the servers in a cluster (which it gets via the vbucket map info) and be able to try all of them, and/or know which ones are alive so that it doesn't have to wait
