With the latest version of the grpc-go library, client.GetMulti blocks forever.

Digging deeper, https://github.com/grpc/grpc-go/blob/master/clientconn.go#L800 is where it's blocking at. Seems like it's an issue with the grpc library, filing it here since it has an impact on Google Cloud products.

Rolling back the grpc-go library resolves this issue.
