在这方面，JAVA确实细致，

至于GO能否在线程池方法有JAVA的优势，

要时间证明。

package main

import (
	"fmt"
	"runtime"
	"sync"
)

var (
	counter int
	wg      sync.WaitGroup
	mutex   sync.Mutex
)

func main() {
	runtime.GOMAXPROCS(1)

	wg.Add(2)

	fmt.Println("Start Goroutines")

	go incCounter(10)
	go incCounter(20)

	fmt.Println("Waiting to Finish")
	wg.Wait()
	fmt.Println("\nFinal Counter: ", counter)
}

func incCounter(id int) {
	defer wg.Done()

	for count := 0; count < id; count++ {
		mutex.Lock()
		{
			value := counter
			runtime.Gosched()
			value++
			counter = value
		}
		mutex.Unlock()

	}

}
