modemlights bug

[Toshio Kuratomi <badger prtr-13 ucsc edu>]

I have a problem with modemlights when I am disconnected from the network.
Namely it gives me the error "ioctl failed" over and over -- this printing
takes up a large chunk of CPU time....

I suspect modemlights needs to check a condition and stop polling if
the network is down.
