why zk.Connect always return no error even if zk server is down?

[elianka]

i found that zk.Connect return no error when zk server is error or down.
i don't know why? i think it should return error when service is unreachable or timeout.
`package main

import (
"fmt"
"time"

    "github.com/samuel/go-zookeeper/zk"

)

func main() {
c, _, err := zk.Connect([]string{"127.0.0.1"}, time.Second) //*10)
if err != nil {
panic(err)
}
fmt.Printf("reach here. no error for zk.Connect! But there is no zk service running \n")
children, stat, ch, err := c.ChildrenW("/")
if err != nil {
panic(err)
}
fmt.Printf("%+v %+v\n", children, stat)
e := <-ch
fmt.Printf("%+v\n", e)
}`

Haven't tried, but my guess is that you should check the returned channel for connection status.
