docs: //------------------------------------------------------------------
  // Switches connected via arbitrary net.Conn; useful for testing
  // Returns n switches, connected according to the connect func.
  // If connect==Connect2Switches, the switches will be fully connected.
  // initSwitch defines how the ith switch should be initialized (ie. with what reactors).
  // NOTE: panics if any switch fails to start.
