golang程序运行时是否可以重新加载动态库？

for {
    t := time.Now()
    fmt.Print(t.Minute(), ":", t.Second(), " ")
    testdll.Testf()
    time.Sleep(time.Second * 2)
}

package testdll
import (
    "fmt"
)
//Testf 
func Testf() {
    fmt.Println("hello I'm version 1")
}

14:29 hello I'm version 1
14:31 hello I'm version 1
14:33 hello I'm version 1
14:35 hello I'm version 2
14:37 hello I'm version 2
14:39 hello I'm version 2
