 * Tee sends a copy of each incoming packet out each output.
 *
 * PullTee's input and its first output are pull; its other outputs are push.
 * Each time the pull output pulls a packet, it
 * sends a copy out the push outputs.
 *
 * By default, Tee and PullTee have an unlimited number of outputs,
 * but you can set a specific number of outputs by giving the optional
 * argument N.
