I think a much more robust solution, which doesn't require any of the tricks mentioned so far in this thread, would be to have a goroutine that loops waiting for a signal (e.g. from a chan) and then uses ListenConfig to create a Listener with a Context. When you want to pause, simply use the Context to cancel the Listener. When you want to resume, send the signal. ...Marvin -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
