Thread vs Groutine
1.创建默认的stack的大小

1. JDK5以后java Thread stack 默认是1M
2. Groutine的stack初始化大小为2K

package goroutine

import (
	"fmt"
	"testing"
	"time"
)

func TestGroutine(t *testing.T)  {
	for i:=0 ; i<10;i++{
		go func(){
			//此时i共享地址，造成竞态，需要加锁
			fmt.Println(i)
		}()
		//内存拷贝
		go func(i int) {
			fmt.Println(i)
		}(i)
	}
	time.Sleep(time.Millisecond * 50)
}
