Pinging an internet address would cause a lot more failures in the 
configuration (many set up nagios on blacknets or behind firewalls). 
Better then to print an alert that it might take some time to run the 
checks (they will end eventually, after all tests are completed, 
although that could take a good long 40 minutes or so).

Ofcourse, blocking ICMP isn't that good idea in the first place. It's 
not called the Internet Control Message Protocol just for fun, you know.
