Remote calls can often hang for a while before they time out. First some background. If ReadyToTrip returns true, CircuitBreaker will be placed into the open state. The circuit breaker will prevent such situations which simply cut off the remaining circuit. The formal grammar of Go uses semicolons ";" as terminators in many productions, but Go programs may omit most of them (and they should to have a clearer, easily readable source; gofmt also removes unnecessary semicolons)..
