Crash!

see.

flush is not goroutine friendly - nsf/termbox-go

NG.

func funcA(){
    while{
        termbox.Flush()
    }
}
func funcB(){
    while{
        termbox.Flush()
    }
}
go funcA()
go funcB()

↓

Change single goroutine.

OK.

flush  = make(chan int)
func termSync() {
    for {
        flg := <-flush
        if flg == -1 {
            break
        }
        termbox.Flush()
    }
}
func funcA(){
    while{
        flush <- 1
    }
}
func funcB(){
    while{
        flush <- 1
    }
}
go termSync()
go funcA()
go funcB()
