-// There are a few caveats:
-//  * Bytes "sent" includes all send attempts and may include
-//    some bytes which were actually never sent over the network.
-//  * Bytes received includes only bytes actually received from the network,
-//    and does not include any bytes read from the the cache.
-//  * Network activity not initiated directly using chromium sockets won't
-//    be reflected here (for instance DNS queries issued by getaddrinfo()).
