We can also use int32 to represent a Boolean value. We can use the integer 0 as false, and 1 as true, creating a thread-safe Boolean condition:

type cond int32

func (c *cond) Set(v bool) {
    a := int32(0)
    if v {
        a++
    }
    atomic.StoreInt32((*int32)(c), a)
}

func (c *cond) Value() bool {
    return atomic.LoadInt32((*int32)(c)) != 0
}

This will allow us to use the cond type as a thread-safe Boolean value.
