def handle_signals
  loop do
    sig = $grpc_signals.shift
    case sig
    when 'INT'
      return false
    when 'TERM'
      return false
    when nil
      return true
    end
  end
  true
end

.trap_signals ⇒ Object

Sets up a signal handler that adds signals to the signal handling global.

Signal handlers should do as little as humanly possible. Here, they just add themselves to $grpc_signals

RpcServer (and later other parts of gRPC) monitors the signals $grpc_signals in its own non-signal context.
