On Unix, we map EPIPE to ERR_CONNECTION_RESET. The error message for EPIPE is
"Broken pipe". So it seems that this error code mapping is correct, even though
I am also not familiar with the Windows ERROR_BROKEN_PIPE error code :-)

       return OK;
     default:
       LOG(WARNING) << "Unknown error " << os_error
                    << " mapped to net::ERR_FAILED";
       return ERR_FAILED;
   }
 }
