The magic behind contexts is that they use a channel but without sending any data over it. Instead, *closing* the channel is a signal to terminate.
This allows you to have multiple goroutines listening on the channel, and they will *all* receive the termination signal, as a broadcast. (It wouldn't work if you sent an item of data on the channel: if you did that, then only one of the receivers would get it) -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
