在主goroutine中，如果我向超出容量的通道发送值，我会出现死锁，但如果我在不同的goroutine发送，则不会出现死锁，为什么？
func main() {
c := make(chan int, 2)
for i := 0; i < 3; i++ {
c <- i
}
}
func main() {
c := make(chan int, 2)
go func() {
for i := 0; i < 3; i++ {
c <- i
}
close(c)
}()
time.Sleep(5 * time.Second)
}
func main() {
c := make(chan int, 2)
for i := 0; i < 3; i++ {
// Blocking operation
c <- i
}
}
By default >>>sends<<< and receives block(!) until both the sender and receiver are ready
