Interesting.... I was fooled.
ifconfig lo:1

lo:1      Link encap:Local Loopback
          inet addr:127.0.0.2  Mask:255.0.0.0
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)


But they never increment.  I dind't notice.  and in the proc table,
there isn't any entry for the virtual interfaces, just stats for the
primary (which includes all virtual).  I am not sure then.
