Description
When the network is down, the external watchdogs are bound to come and kill the machine.
Protect ourselves against these random incompletes by stopping the execution early and exiting.
The current plan was to allow the configuration of a host to ping before executing a new binary to make sure that the network is still up. The host to ping should be specified in igtrc. If none are specified, no pings should be made.
